Bug 281531 – [ Sequoia wk2 ] two accessibility/mac/ pdf tests are a consistent timeout

• Component: New Bugs
• Status: NEW

[Karl Rackler]

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@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
