In WebContentsImpl::GetPendingZoomLevel, it's possible for the RenderWidgetHost parameter to correspond to an independently zoomed RenderFrameHost that isn't for a main frame. An example is when kPdfOopif is enabled. In theses cases GetPendingZoomLevel should not look at the pending entry in the RenderFrameHost's NavigationController, as it will be for the main frame, which is by definition outside the independently zoomed subtree in this case. This CL modifies GetPendingZoomLevel so that, if the target RenderFrameHost isn't a main frame, it ignores any pending entries on the associated navigation controller.

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

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.
