fix(Modal): updated logic to set aria-hidden for tearsheets - #12627
Conversation
WalkthroughThe modal implementation now tracks open modal backdrops per append target. Accessibility handling keeps only the topmost modal in each target-specific stack visible while preserving popper elements. Tests and the basic example cover nested and independent modal behavior. ChangesStacked modal accessibility
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to Changing where an open modal is appended can leave the previous target with stale accessibility and backdrop state, potentially affecting surrounding content and keyboard behavior. The PR is not merge-ready until the old target is cleaned up before registering the new one. Sequence Diagram(s)sequenceDiagram

- Line 72: Scope modal stack state and backdrop cleanup per appendTo target
instead of using the global Modal.openModalStack array. Update the stack
handling and sibling aria-hidden logic near the modal open/close flow, including
the backdropOpen cleanup, to read only the current target’s stack, remove empty
target entries, and preserve independent behavior for distinct targets; add
coverage using two separate appendTo elements.

- Around line 110-120: Update toggleSiblingsFromScreenReaders to avoid calling
Modal.getStackForTarget when hide is false, since that creates and retains a
stack for unopened modals; read the existing entry from Modal.openModalStacks
and return when none exists, while preserving stack creation for the open path.
Add coverage for unmounting a closed modal using a custom appendTo target.
