Explictly assigning. A CL you landed tripped one of the speed metrics we measure in the lab. If this is the first time this has happened to one of your CLs, or if it's been a while, please read: https://chromium.googlesource.com/chromium/src/+/master/docs/speed/addressing_performance_regressions.md We're looking for one of the following: 1. Justification via explanation 2. Plan to revert or fix 3. Angry rage throwing of equipment at my head Just be aware that I'm trained in trumpet playing and First Aid and am not afraid to use it. Note: This was a bulk edit message and not very personal.

Sorry, the change which caused this regression was reverted for other reasons. Closing this out. |
