            Bug ID: 281531
           Summary: [ Sequoia wk2 ] two accessibility/mac/ pdf tests are a
                    consistent timeout
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: New Bugs
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: rackler at apple.com

Description:
accessibility/mac/basic-embed-pdf-accessibility.html
accessibility/mac/iframe-pdf.html

These tests have been timeouts since Sequoia bring up.

The first timeout I see on the flakiness dashboard was on 9/20/2024 at 283998 at main.  That commit deals with subgrids when we try to resolve a grid-area to line names and does not appear to contribute to the regression.

This issue can be reproduced using command:
run-webkit-tests --release --no-retry --force --iterations=1 accessibility/mac/basic-embed-pdf-accessibility.html accessibility/mac/iframe-pdf.html
