Set Hardware Cursor doesn't refresh when clicking and holding in PIE when dragging out and back in

The SetHardwareCursor function sometimes doesn't update when clicking and holding the left mouse button on a widget component, like a button, and causes the cursor to default back to its normal icon if it has been changed.

• Open attached repro project
• Press Play to Play in Selected Viewport
• Press and hold the left mouse button over the button(widget)
• Move the cursor outside of the window and back inside again, while still holding the mouse button down. After few tries SetHardwareCursor will fail to change the cursor
• You can release the mouse button, move the cursor around, and even do a few clicks but SetHardwareCursor still wont change the cursor back.
• After leaving the window and re-entering again, SetHardwareCursor will change the cursor

Result: SetHardwareCursor won't change the cursor back after leaving window when holding down left mouse button

Expected: SetHardwareCursor keeps the cursor the same when left clicking and leaving the window
