GetMouseButtonUp(0) doesn't return true sometimes



How to reproduce:
1. Open the attached project ""
2. Open the "SampleScene" Scene
3. Enter Play Mode
4. Click until the cube doesn't turn back to white from red

Expected result: GetMouseButtonUp(0) returns true and cube turns white
Actual result: GetMouseButtonUp(0) doesn't return true and the cube stays red

Reproducible with: 2020.3.12f1, 2021.1.11f1, 2021.2.0b1

- The bug happens randomly
- On macOS, if the function doesn't return true on click then the return true is delayed until any other input, for example - mouse movement
- On Windows when GetMouseButtonUp(0) doesn't return true the next GetMouseButtonDown(0) doesn't return true as well
- Tried >1000 clicks on 2018.4.36f1 and 2019.4.28f1, but the problem didn't occur, however since the bug is random it's not certain that it's not reproducible with those versions

  1. Resolution Note:

    Postponing until further notice due to higher priority needs. We hope to revisit this at a later time.

    I faced this issue on macOS in Unity Editor only.
