Fix regression in BubbleContentsWrapper.

The BubbleContentsWrapper code was moved from RenderViewHostChanged to
RenderFrameHostChanged, which are supposed to be identical events.
Unfortunately, in some specific cases (which we are actually aiming to
remove), the RenderViewHostChanged event was being fired and the code
in this class depended on that behavior. It turns out that this behavior
does not exist with RenderFrameHostChanged, so it was not as safe of a
transformation as I expected. PrimaryPageChanged, which is long term the
best event to listen to for when a WebContents navigates the main frame,
also has the behavior BubbleContentsWrapper is looking for. This CL moves
the implementation to this event instead of RenderFrameHostChanged.

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.
