Accessibility: Not able to navigate to dates again in the DatePickerController after selecting a date in the previous month about fluentui-apple

@lcapkovic in case you have insights

This only repros in an NSPopover for me. When paging to any month, the new CalendarView doesn't seem to get added to the key view loop, so you can't navigate to it using tab anymore.

I found forcing a key view loop recalculation in the paging animation completion handler fixes it, but I'm not sure if that's the best solution.
The quick fix is to add self.window?.recalculateKeyViewLoop() at the end of the completionHandler in DatePickerView.swift line 343.

When presented in a popover, self.window will actually be the system-created NSPopoverWindow, not the main NSWindow where we have auto recalculating enabled. Maybe NSPopovers just don't auto recalculate the key view loop by default?

fwiw I made a quick sample app that presents an NSPopover and the NSPopoverWindow has autorecalculatesKeyViewLoop set to true by default. Certainly possible something about animations is tricking the key view loop and it's calculating the loop before the animation has committed - maybe we could contrive a scenario like that to see if it's an Apple bug?
