Reland "Give parent widget a chance to process accelerators"

This reverts commit 71efa534c89c7ca5112738f0b3f790a35c9e8159.

Reason for revert: The regression b/404763413 no longer repros. This CL
will also fix the issues with omnibox AIM popup b/460262043 (keyboard
accelerators are not being forwarded to the parent widget which causes
events like Ctrl+T to not be processed)

> > Instead of looking for a bubble dialog delegate to give anchor_widget

> > and add a virtual method that widget delegate sub-classes can override
> > to prevent this behavior.

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.
