Description: pdf/pdf-in-embed-with-root-page-zoom.html The test was added at 283250@main and had been a consistent failure since then, but a test expectation was added simultaneously for [ Sonoma+ ] to suppress it. Later, at 287995@main, a rebaseline was done that did not resolve the consistent failure, and the test expectation was removed simultaneously, causing the failures to be reported to the flakiness dashboard. At 288397@main, the ENABLE_UNIFIED_PDF_SELECTION_LAYER was removed, and the test behavior changed. The test began flaky failing and timeout while running the test fully-parallel. This issue can be bisected to 288397@main using the command: run-webkit-tests --release --no-retry --force -f --exit-after-n-failures 1 --iterations=1000 pdf/pdf-in-embed-with-root-page-zoom.html **NOTE** At 288396@main, you can reproduce the issue using the command run-webkit-tests --release --no-retry --force --exit-after-n-failures 1 --iterations=1000 pdf/pdf-in-embed-with-root-page-zoom.html but at 288397@main you have to add the -f argument to reproduce the failure, i.e., run-webkit-tests --release --no-retry --force -f --exit-after-n-failures 1 --iterations=1000 pdf/pdf-in-embed-with-root-page-zoom.html History: https://results.webkit.org/?suite=layout-tests&test=pdf%2Fpdf-in-embed-with-root-page-zoom.html Diff: -
