Description

Widget appears to take focus on mouse up and this appears to have functioned differently in earlier versions

Steps to Reproduce
  1. Open the attached project
  2. Play in editor
  3. Right Click (not over the scroll box widget) and hold
  4. Notice that a white widget with text appears (Expected)
  5. Release (not over the scroll box widget)
  6. Notice that the white widget disappears (Expected)
  7. Right Click (not over the scroll box widget) and hold
  8. While holding move the widget over a visible button in the scroll box
  9. Release the right mouse button
  10. Notice that the white widget does not disappear this time (Not Expected)

Expected: In 4.10 when using this same setup the white widget would disappear on release when hovering other visible widgets. It is expected that the same would still be true
Result: The white widget does not disappear due to the widget grabbing focus on mouse up
