I've tried bisecting this on my Linux box. There may be a regression that increased the flakiness but even 100 commits back flakiness was already at 1%. I'll leave this one to the experts.

removeformat.html has may tests cases, 150+, in external/wpt/editing/data/removeformat.js.

We should split them into small pieces to avoid timeout in try bot.

[Sheriff] wpt/editing/run: Allow removeformat.html to timeout again.

In https://chromium-review.googlesource.com/c/chromium/src/+/1205917:
"Set longer timeout to all tests in wpt/editing/run/", the test
external/wpt/editing/run/removeformat.html 's Timeout expectation was
removed (along with reference to crbug.com/813098). Likely as a result,
WebKit Linux Trusty Leak is flaking in webkit_layout_test for
removeformat.html. This CL undos the particular change to remove noise.
