The notify panel in the animation editor doesn't currently support windows display scaling. If the user changes the display scale to something like 150% then selection of notifies is inaccurate. The code responsible looks like it may be SAnimNotifyPanel::RefreshMarqueeSelectedNodes.

Steps to Reproduce
  1. Set windows display scale to 150%
  2. In the editor open an anim sequence in persona
  3. Add 3 or 4 notify tracks
  4. In the bottom notify track, add a notify (a notify state best shows the issue)
  5. Attempt to marquee select the notify
    1. Expected behaviour: as soon as the marquee selection overlaps with the notify rect the notify should be selected
    2. Actual behaviour: the notify does not get selected when the marquee selection overlaps with just some of the notify rect, the entire notify or more needs to be overlapped before the selection is registered (see screenshot)
