The following four tests are are flaky text failures on macOS: imported/w3c/web-platform-tests/editing/other/insertparagraph-in-child-of-html.tentative.html?designMode=on&white-space=normal imported/w3c/web-platform-tests/editing/other/insertparagraph-in-child-of-html.tentative.html?designMode=on&white-space=pre imported/w3c/web-platform-tests/editing/other/insertparagraph-in-child-of-html.tentative.html?designMode=on&white-space=pre-line imported/w3c/web-platform-tests/editing/other/insertparagraph-in-child-of-html.tentative.html?designMode=on&white-space=pre-wrap At the filing of this bug these were occurring on wk1, wk2, Intel, and Apple Silicon Macs on Ventura and higher, and according to the history they have been flakes for a long time > 5000 commits back. Filing all of these together as they seem to be slightly different versions of the same test.

I have been trivially been able to reproduce each of these test failures on macOS Sequoia Production ToT running the test as follows: run-webkit-tests <Insert_Test_Here> --iterations 1000 I was able to reproduce the failures on average 3 times with each test running per 1000 iterations.
