Automatically adding ccs based on suspected regression changelists:

S13nServiceWorker: avoid to run idle callback when running queued tasks by shimazu@chromium.org - https://chromium.googlesource.com/chromium/src/+/e54263e71531ab21bf72dbd48e5ebc32be717306

If this is incorrect, please let us know why and apply the Test-Predator-Wrong-CLs label.

This is a serious security regression. If you are not able to fix this quickly, please revert the change that introduced it.

If this doesn't affect a release branch, or has not been properly classified for severity, please update the Security_Impact or Security_Severity labels, and remove the ReleaseBlock label. To disable this altogether, apply ReleaseBlock-NA.

Assigning per regression range, as this is the only vaguely-suspicious CL in that range, but feel free to re-assign if the CL is not the culprit.

Shimazu's CL doesn't seem relevant, either...

This could be HTMLImport's issue, or, maaaaaybe Oilpan's. Someone on those areas
