Unexpected exit from always on top when enter is pressed

[HerrickSpencer]

Possible Reason
This is likely due to focus. the default focus is on the "Back to full view" button when the app enters alwaysontop mode. So if the enter or space key is hit, it will fire this button. Fix would be to move the focus off this button when the app enters alwaysontop mode.

Describe the bug
when in Alwaysontop, app will fall out of always on top mode when enter is pressed

Steps To Reproduce
Steps to reproduce the behavior:

1. Go to standard mode
2. Click on always on top button on right next to "Standard"
3. use keyboard/num pad to enter a calculation ( ending in enter key)
   3(a) - alternate - just hit enter key
   3(b) - alternate - just hit space key

Expected behavior
app should stay in always on top mode

Actual behavior
app falls out of always on top mode

Yep, good catch! It seems this behavior regressed. Upon entering always on top, focus should land in the display area (just like when opening Calculator from Start).
