The following revision refers to this bug:

commit 2c857442fcadb84aef4a606dad44fb5050de478b

Fix bug of black bottom toolbar in landscape mode.

When tab grid is opened in landscape mode on iPhone, the bottom toolbar
has a black background instead of a transparent background. This is
caused by setting toolbar background to UIColor.blackColor in
TabGridBottomToolbar.hide(). This CL fixes it and doesn't affect the
tab grid transition animation.

This CL also sets the background for remote pages of tab grid in
TabGridBottomToolbar.updateLayout(), which solves another potential bug.

Verified on iPhone XSMAX iOS 12.0.1 on build 73.0.3680.0 Canary .
Tabs in Tab Switcher mode in landscape orientation looks good.
