Automatically applying components based on crash stacktrace and information from OWNERS files.

Automatically assigning owner based on suspected regression changelist https://chromium.googlesource.com/chromium/src/+/ffb5de3934abd4e16399b2f79e7100823c6076fd (Don't propagate cmdline flags that are not read by renderer processes.).

If this is incorrect, please let us know why and apply the Test-Predator-Wrong-CLs label. If you aren't the correct owner for this issue, please unassign yourself as soon as possible so it can be re-triaged.

The CL pointed out in #c2 (ffb5de3934abd4e16399b2f79e7100823c6076fd - r529051)
stopped propagating some cmdline switches from the browser process to the
renderer process:
- switches::kForceWebRtcIPHandlingPolicy
- switches::kDisableGestureRequirementForPresentation
- switches::kDisableLocalStorage
- switches::kDisablePinch
- switches::kDisableSmoothScrolling
- switches::kEnablePinch
- switches::kEnableSmoothScrolling
- switches::kEnableStatsTable
- switches::kMainFrameResizesAreOrientationChanges
- switches::kSitePerProcess

I've just double-checked that these cmdline flags are only dereferenced
in the browser process (e.g. in code under //content/browser) and never
in the renderer process.  Therefore, the CL above should be a no-op
(i.e. shouldn't cause a ClusterFuzz bug).

FWIW, I cannot reproduce the ClusterFuzz failure at ffb5de3934abd4e16399b2f79e7100823c6076fd:
    $ git checkout ffb5de3934abd4e16399b2f79e7100823c6076fd
    $ gclient sync
    $ /google/data/ro/teams/clusterfuzz-tools/releases/clusterfuzz reproduce 5274750654611456 -c -j 500 -l 25 --skip-deps
    ...
    UnreproducibleError: The crash cannot be reproduced after trying 3 times.
This further reinforces the Test-Predator-Wrong-CLs label.

BTW: I also cannot reproduce the ClusterFuzz failure at ToT (163641576c99ccaff013d589044f2c31bfdae6cd / r163641576c99ccaff013d589044f2c31bfdae6cd) so maybe the failure is intermittent?

yosin@, could you PTAL and help triage as one of third_party/WebKit/Source/core/editing/OWNERS?

(I am removing myself as an owner, as explained in #c3)

ClusterFuzz testcase 5274750654611456 is flaky and no longer crashes, so closing issue.

If this is incorrect, please add ClusterFuzz-Wrong label and re-open the issue.
