How to reproduce:
1. Create an empty Project
2. Open the Windows Task Manager and take note of the Memory usage of the Editor
3. Navigate to “Window /UI Toolkit /UI Builder” and open the UI Builder window
4. Ensure that the window is docked inside the layout of the Editor
5. Then repeatedly press the *shift and space keys* to minimize and maximize the UI Builder window
6. Observe the Editor’s Memory usage inside the Task Manager application
7. Repeat steps 5 and 6 if necessary

Expected result: Memory usage doesn’t change in a significant way
Actual result: Memory usage increases by set increments and never decreases

Reproducible in: 2021.3.45f1, 2022.3.51f1, 6000.0.25f1, 6000.1.0a3

Reproducible on: Windows 11
Not reproducible on: No other environments tested

Note: The memory usage differs between versions. In 2021 streams maximizing the window results in a way lower memory usage increase than in 6000
