From d8cf933d6764f6e18a1b2382ca1f7900f4993dfd Mon Sep 17 00:00:00 2001 From: Molecule AI Fullstack Engineer Date: Wed, 13 May 2026 15:41:10 +0000 Subject: [PATCH] fix(TermsGate): aria-hidden backdrop, aria-disabled submit button, ellipsis UX MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Backdrop is now decorative sibling (aria-hidden=true) so screen readers land on the dialog landmark directly. The submit button uses aria-disabled=true instead of disabled so it stays in tab order while the POST is in flight. The button label switches to "…" (ellipsis) during submission and stays there until the server confirms acceptance — the catch block no longer resets submitting=false, which previously caused the ellipsis to flicker out while the dialog was still visible. Add three regression tests covering ellipsis display, aria-disabled presence, and the absence of a disabled attribute during submission.
