Only notify when size acutally changed in OnHostResizedInPixels

This method is called also when the scale factor MAY change and may not
results in the actual size change. In that case, we should not call
the observer which may close auto fill window.

This CL intentionally still try to update the compositor to minimize the
risk of merging back to m104.

Bug: 1329481

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.
