Bug: 397767033, 413768466
Original change's description:
> [Message Sync] Update last seen timestamp when clearing dots locally
>
> Currently when tab dots are cleared via another entry point such
> as clicking X on collaboration message card on mobile, we clear
> the tab dots, but it doesn't get sent over to sync. In this CL,
> we do that by updating the last seen timestamp.
> A public method was added to TabGroupSyncService for this purpose
> that can be invoked from UI callsites.

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.
