Fix for an issue where user isn't able to mute tab

The main issue is we always attempt to delete the current
site URL from the exception list if the target setting matches
the default value. This has two issue,

(1) First, the site URL might not exist in the exception list
since the override is from a less specific URL e.g. wildcard.

(2) Second issue is we have to add the specific URL to achieve
the desired behavior if there is a less specific rule present
in the exception list.

Additional the CL also contains a small fix for the issue
where adding an exception rule like wildcard isn't causing
settings to refresh correctly to show the added entry.
This issue is fixed in site_list.ts to handle the appropriate
notification triggered from the handler.

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.
