Fix landed 6.6 and will be backported to 6.5. Closing port 6.4 to reduce risk of regressions.

Steps to reproduce:

Actual results: The ListView element is rendered in solid black after redocking the UI Builder window

Expected results: The ListView element is rendered the same way as in Step 3

Reproducible with versions: 6000.0.65f1, 6000.3.1f1, 6000.4.0b1, 6000.5.0a3

Tested on (OS): macOS 26.1

Notes:

If the UI Builder window is closed and then opened, the LIstView will be rendered normally until the project is reopened
