Subject: fix: Adjust caption-removing style call
There is a SetWindowLong call that removes WS_CAPTION for frameless
windows, but Electron uses WS_CAPTION even for frameless windows,
unless they are transparent.
Changing this call only affects frameless windows, and it fixes
a visual glitch where they showed a Windows 7 style frame
during startup.
The if statement was originally introduced by
https://codereview.chromium.org/9372053/, and it was there to fix
a visual glitch with the close button showing up during startup
or resizing, but Electron does not seem to run into that issue
for opaque frameless windows even with that block commented out.
