[ScrollUnification] Cannot scroll <select> popup

Select html element uses WebPagePopupImpl widget which handles scroll
gestures differently than other widgets. We need to handle scroll differently.
Because this is a simple widget, we'll try to use the underlying
LayoutViewport to scroll directly.

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.

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.
