Ensure caption button height for maximized windows isn't too large.

Pre-Refresh a maximized window had a very condensed tabstrip, so it made
sense to set Windows 10's caption button height to (slightly less than)
the tabstrip height. Refresh tabs are much taller though, so now they
look way too big. This patch caps their height at the restored height,
since that's what Windows does in the same case.
