Frame Debugger cannot be enabled when opened from UI Toolkit Details module of Standalone Profiler

Steps to reproduce:

1. Create a new 3D URP project
2. Open Window > Analysis > Profiler (Standalone Process)
3. Click on the "UI Toolkit Details" module to focus on it
4. Click on the "Open Frame Debugger" button in the panel
5. Observe the opened Frame Debugger

Actual results: The Frame Debugger opens showing "Frame Debugger requires at least one available Game (Play Mode) window" and cannot be enabled, even with a Game view open in Play mode

Expected results: The Frame Debugger should open and capture the main editor's Game view, or the "Open Frame Debugger" button should be disabled in the standalone Profiler

Reproducible with versions: 6000.6.0a7

Can’t test with versions: 6000.5.0b12 ("UI Toolkit Details" module not available)

Tested on (OS): Windows 11

Notes:

• Only reproduces with the Standalone Process Profiler; opening the Frame Debugger from the basic Profiler with an identical setup works
• If such use is not supported the error message should be more clear
