[0.4.14][WIN32SS] Repaint the whole window frame on some style bits set (#3199)

Browse source 
This fixes the ReactOS Calculator buttons disappearing in CORE-16827

It once regressed by 0.4.13-dev-221-g
2161dd85dc
which did aim to fix CORE-15934.
Noteworthy that releases/0.4.12 was never affected although I fixed CORE-15934
there as well, but *not* with the fix that went into master later!

fix picked from commit 0.4.15-dev-1197-g
