Fix OEM menu issue

Fix OEM menu issue

- Some OEMs don't let us change the background, so the padding is incorrect.
- Also including sizing the menu too large causes clipping.

This seems to work... sigh.  There's no best solution and it's not optimal
(doesn't cut the items in half in some cases), but it at least never leaves a
user unable to fully scroll to buttons.

LGTM... sigh...
