Description

The left mouse button press does not act as expected when the input setting "Default Viewport Mouse Capture Mode" is set to "Capture During Right mouse Down"

TLDR:

Left mouse button press fires when:

  • Right mouse is held down
  • Left mouse is double clicked

Left mouse button does not fire when:

  • Left mouse is pressed by itself once (meaning not double clicked)
Steps to Reproduce
  1. Download the attached project
  2. Open the project
  3. Open the Untitled map
  4. Play In Editor
  5. Press and release the left mouse button once
  6. Notice that only the release fires
  7. Hold the right mouse button down
  8. Press and release the left mouse button
  9. Notice that the left mouse press fires this time (as well as the release)
  10. Release the right mouse
  11. Double click the left mouse

Result: The Left mouse press only fires when double clicking or when the right mouse button is held down.
Expected: The left mouse press would fire when ever the left mouse button is pressed
