Start BeginMainFrame on empty documents

This change removes a dubious line in
LocalFrameView::BeginLifecycleUpdates() where we never
began updates for empty documents. There is no reason for this,
as empty documents would not cost anything to update and for the
case of certain content (empty iframes, some window.open() cases)
it results in script never executing to populate the frame.

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.
