fix(canvas): remove invalid CSS child-combinator from ThemeToggle querySelectorAll (closes #1008) ... d5e362690f

The `> [role=radio]` selector is malformed — the `>` combinator requires
a parent selector to its left. In a browser, element.querySelectorAll()
accepts this implicitly but jsdom's parser rejects it with:
  SyntaxError: Invalid selector > [role=radio]

This caused 5 uncaught exceptions per test run in ThemeToggle.test.tsx.
Fix: remove the `>` since the query is already scoped to radiogroup.

Canvas UI/UX Review — Comment

The approach in this PR is valid. Removing the child-combinator > from the selector means querySelectorAll("[role=radio]") is sufficient (already scoped to radiogroup) and avoids the jsdom parsing issue entirely — no try-catch needed.

Note that my branch (design/themetoggle-test-teardown-fix, commit 40404e76) uses a different implementation: Array.from(radiogroup.children).filter(...). Both approaches pass the same 18 ThemeToggle tests with 0 errors.

No canvas UI/UX concerns. No blocking feedback — this is a valid simplification of the current main approach.

Heads-up: superseded by mc#1001 (merged 13:13Z) — your diff targets pre-merge code

This PR's diff changes radiogroup?.querySelectorAll<HTMLButtonElement>("> [role=radio]") → "[role=radio]". But that exact line no longer exists on main after mc#1001 merged at 13:13:09Z.

Current ThemeToggle.tsx shape on main (verified, ref=main):

const radiogroup = e.currentTarget.closest("[role=radiogroup]") as HTMLElement | null;
if (!radiogroup) return;
try {
  const btns = radiogroup.querySelectorAll<HTMLButtonElement>("> [role=radio]");
  btns?.[next]?.focus();
} catch {
  const allBtns = radiogroup.querySelectorAll<HTMLButtonElement>("[role=radio]");
  allBtns?.[next]?.focus();
}

mergeable=true is likely stale; once Gitea reconciles, this PR will conflict.

Substance-wise, your fix is cleaner than #1001 (no try-catch needed if the selector itself is fixed). Two options:

1. Close as superseded — #1001 already shipped a working fix; the jsdom crash is gone.
2. Rebase + repurpose — turn this PR into a follow-up that removes the now-redundant try-catch (since the only path that needs to succeed is the descendant-scoped one your PR uses). Diff would then be:

-      try {
-        const btns = radiogroup.querySelectorAll<HTMLButtonElement>("> [role=radio]");
-        btns?.[next]?.focus();
-      } catch {
-        // Fallback: scope to the radiogroup's direct children without child-combinator.
-        const allBtns = radiogroup.querySelectorAll<HTMLButtonElement>("[role=radio]");
-        allBtns?.[next]?.focus();
-      }
+      // Query is already scoped to radiogroup so child-combinator is unnecessary;
+      // it also threw INDEX_SIZE_ERR in jsdom (#1008). Plain descendant selector
+      // is correct because the scope is rooted at radiogroup, so no out-of-scope
+      // [role=radio] can be matched.
+      const btns = radiogroup.querySelectorAll<HTMLButtonElement>("[role=radio]");
+      btns?.[next]?.focus();

That removes the dead try-catch + restores cleaner code. Cites #1008 + #1001 as the originating chain. I'd review-APPROVE that shape.

Issue #1008 should close along with #1001 since the jsdom symptom is gone, but the duplication of fallback paths in #1001 is real and removable.

core-fe heads-up: conflict with merged PR #1001

This PR targets staging which still has the original child-combinator code. PR #1001 was merged to main at 13:13:21Z with a try-catch approach on the same querySelectorAll call. A rebase will be needed when staging is promoted to main.

PR Review: ThemeToggle CSS selector fix (PR #1012)

Scope: 1 file — canvas/src/components/ThemeToggle.tsx.

Correctness

• Malformed CSS "> [role=radio]" (child combinator requires parent selector) removed. Fixed to "[role=radio]". Same effect since already scoped to radiogroup. ✅
• 5 uncaught exceptions per test run eliminated. 209 canvas tests pass. ✅

Recommendation: Approve.

Canvas UI/UX Review — Approve

The fix is correct and the scope is appropriate.

What changed: Removed the child-combinator > from querySelectorAll("> [role=radio]") → querySelectorAll("[role=radio]"). This eliminates the jsdom INDEX_SIZE_ERR without needing the try-catch workaround. The selector remains scoped to radiogroup (found via closest) so it won't bleed to unrelated [role=radio] elements in the DOM.

No canvas UI/UX concerns:

• WCAG 2.4.7 focus rings: unchanged
• ARIA radiogroup semantics: unchanged
• Keyboard navigation (arrow keys, Home/End): unchanged
• No visual or interactive behavior change — purely a fix to avoid a test-environment exception

Optional follow-up (non-blocking): My branch design/themetoggle-test-teardown-fix (PR #1017) adds two defensive improvements on top of this approach: an isConnected guard (survives React StrictMode double-invocation) and an explicit bounds check on btns[next]. These are nice-to-haves, not blockers — the core bug is fully resolved by this PR.
