Unity Editor frame rate drops when making many successive inputs

Reproduction steps:
1. Create a new 3D Unity project
2. Open the Profiler (Window -> Analysis -> Profiler)
3. Change the Profiler window to record Editor performance
4. Start pressing the keyboard buttons rapidly

Expected result: Consistent and stable performance
Actual result: Performance degradation

Reproducible with: 2021.2.0a16, 2021.2.18f1, 2022.1.0b13, 2022.2.0a9
Not reproducible with: 2019.4.37f1, 2020.3.32f1, 2021.2.0a15

Note:

• To document the degradation of performance the FPS metric in the Profiler was used
• 2019.4 and 2020.3 at the lowest went to 100FPS whereas later streams went as low as 60FPS and rarely to 30FPS
• Reproduction is somewhat inconsistent, to reproduce do step 4. then promptly stop and start step 4. again, doing this in intervals helps with reproduction
