If you need an exemption to this rule, contact Hixie on the #hackers channel in Chat (don't just cc him here, he won't see it! He's on Discord!). If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix? Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. |

Fixes #101535. The extra arguments were previously hidden behind the
debugProfileBuildsEnabled,debugProfileLayoutsEnabled, anddebugProfilePaintsEnabledflags. Now the additional arguments. will be hidden behind their own respective debugging flags -- the additional event arguments make the timeline trace very heavy.debugProfileBuildsEnabled,debugProfileLayoutsEnabled, anddebugProfilePaintsEnabledare useful without the extra arguments, so we want to make these features useable without severely impacting the app's performance due to tracing overhead.
