Description

When clicking on an object EndInputTouch sometimes fires on the press instead of the release. This was not an issue in 4.19.2 (CL-4033788) and is a regression. However the functionality doesn't appear to work at all in Main 4.21 (CL-4370874)

This was tested and reproduced in 4.20.2 (CL-4302132).

Steps to Reproduce
  1. Open the UE4 Editor and create a Top Down template project
  2. In Project Settings enable Input > Use Mouse For Touch
  3. Choose one of the grey cubes in level and create blueprint from it using blue button Blueprint/Add Script
  4. In the Blueprint create an EndInputTouch event and connect it to a Print String
  5. Play, run around the cube and then click on it

Results: EndInputTouch fires when object is pressed and released.

Expected: EndinputTouch event will activate only when mouse button is released on the object.
