Why is this needed?

By default, ShellStackingClientAsh creates root window of size (100, 100) in
content/shell/shell_stacking_client_ash.cc
ShellStackingClientAsh::GetDefaultParent function, resulting in root window of
dimension (100,100). Above call will set the root window size to WebView window
size.

Shouldn't the size passed to CreateWindowWithBounds be used?

Done.
