Event Timing - Fallback artificial events ending time to processingEnd

* Previous undesired outcome: clicking on MacOS selectmenu dropdown can
  report arbitrarily long INP.
* Root cause: MacOS use a special external popup class which dispatch
  artificial events outside of WidgetInputHandlerManager and result in
  not breaking presentation promise.
* This CL address it by: identifying artificial pointerups & clicks
  from event timing and reporting the processingEnd as entry's ending
  timestamp rather than an incorrect arbitrarily long presentation
  delay.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.

If you found a bug, please file it at https://crbug.com/new.
