Tip-of-the-day window steals input even when another window has focus
2.9.20151111 OS X 10.10.5
For instance, I might get a tip about creating new keyboard shortcuts, and I may go to Prefs -> Keys to try it out. If I hit the + button and then see something else I want to check out first so I hit [esc] to close the sheet for new keyboard shortcuts, the [esc] input closes the tip-of-the-day window instead of the sheet, even though the field in the sheet has focus.
I've also had this happen when another app has focus. In both cases it is surprising.
