tablet_mode: Fix crash on dragging split divider at tablet mode

This CL fixed the crash when quickly dragging the split bar at tablet
mode with multiple displays by setting the property kLockedToRootKey to
true for the native window of the split bar. By doing this, we can make
sure that the split divider will always stay at the the display where it's created.

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.
