Cannot move in Blueprint window on Breakpoint hit (only when 'use mouse as touch' is enabled)

When triggering a breakpoint while Use Mouse for Touch is enabled the navigation functionality is lost within that Blueprint.

1. Create a blank project.
2. In a Blueprint, add a breakpoint anywhere.
3. Press PIE and trigger the breakpoint.
4. Attempt to navigate the Blueprint window using the mouse. (right click and drag around)
5. Stop PIE.
6. In Play -> Advanced settings, turn ON "Use Mouse for Touch"
7. Launch PIE and trigger the breakpoint again.
8. Attempt to navigate the Blueprint window using the mouse. (right click and drag around)

Result: Right click to drag no longer works for navigation like it did earlier.

Expected: Navigation should work as it did before Use Mouse for Touch was enabled.
