REPRODUCTION:
Reproduced on macOS Tahoe 26.2 with the following:

run-webkit-tests --force --no-retry --release --iterations 1 http/tests/site-isolation/accessibility/cross-process-search-nested-iframes.html http/tests/site-isolation/accessibility/hit-test-returns-remote-frame.html http/tests/site-isolation/accessibility/hit-test-resolving-remote-frame.html 

Note: http/tests/site-isolation/accessibility/cross-process-search-nested-iframes.html must run before to cause failure.

I am going to mark these tests as failure while they pend investigation.
