Steps to reproduce:

1. Create and open a new project
2. Install AI packages
3. Open Window -> Analysis -> Profiler (Standalone Process)
4. Record some data
5. Click on any sample and enable "Calls" in the Profiler Hierarchy
6. Select any one of the calls
7. Press "Ask AI Assistant" and press on the up arrow
8. In the opened AI Assistant window, click on the prompt field

Actual results: Nothing happens

Expected results: Flashing caret is displayed, indicating a focused on field

Reproducible with versions: 2.8.0-pre.1 (6000.4.8f1, 6000.5.0b9, 6000.6.0a4)

Can’t test with versions: 6000.0.75f1 (No AI Assistant package), 6000.3.16f1, 6000.6.0a5 (AI Assistant package errors)

Tested on (OS): Windows 11 Pro (25H2)

Notes:

• Unable to test for regression due to incompatibilities between the Editor and older AI Assistant packages
• Regular embedded Profiler does not have this problem
