Reproduction steps:
1. Open attached project "InputActuatedTest.zip" and scene "SampleScene"
2. Enter Play Mode
3. In Project window, open Assets/InputSystemTest.cs
4. In Visual Studio, Attach to Unity
5. In Visual Studio, setup conditional breakpoint on line 21, when 'bool pressed' is true
6. In Game View, press a keyboard key
7. In Visual Studio, continue 5 times, observe the value of pressed variable
8. In Visual Studio, disable or remove the conditional breakpoint, continue
9. In Game View, observe the text value
10. In Game View, press any key, observe text value change

Expected result: In step 7, the variable value does not remain true, after removing the breakpoint, the text value changes to 'false'
Actual result: In step 7, the variable value remains true, after removing the breakpoint, the text value remains to 'true' until another key is pressed

Reproducible with: 1.1.0-preview.3 (2019.4.27f1, 2020.3.10f1, 2021.1.9f1, 2021.2.0a17)
Could not test with: 2018.4.35f1 (compilation errors break project)

Notes:
Sometimes, after step 10, the text value does not change to 'false', instead, it remains 'true'
