Listen For Input Action firing erroneously.
Confirmed in 4.26 MAIN @ CL 11536993
User provided repro project attached.
Result: Widget will be destroyed from 3.4 callback you can press and hold Q again and click on button, nothing happens, its worked as designed for second time. You can restart PIE and repeat all from step 6. Widget will be destroyed on first mouse click, but will be fine for second time
Expected: Widget destroys only when you release Q
