Subject: [PATCH] fix(canvas/a11y): restore aria-hidden on backdrop div after
 cherry-pick conflict
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Cherry-pick from #1744 left the backdrop div without aria-hidden="true"
(the outer dialog div got it instead). Re-apply aria-hidden="true" to
the backdrop div so screen readers skip the clickable overlay layer.

Also revert test assertion from bg-black → bg-black/70 to match the
exact class applied to the backdrop div.
