Graph Toolkit shortcuts that require multiple modifier keys do not trigger after narrowing the Selection via Graph Inspector

Steps to reproduce:

1. Open the attached project
2. Open the Test.texmkr graph asset
3. Select the 4 Variable Nodes and the 4 connecting wires
4. In the Graph Inspector Overlay, narrow the selection to Nodes only
5. Try triggering the Convert To Constant shortcut (Default on Windows -> Ctrl+Shift+T)

Actual results: Convert To Constant action is not performed

Expected results: Shortcut is triggered and the  Convert To Constant action is performed

Reproducible with versions: 6000.4.0b8, 6000.5.0a6

Can’t test with versions: 6000.0.67f1 6000.3.8f1 (GTK is not available as a built-in module)

Tested on (OS): Windows 11, macOS 26.2 

Notes:

• Shortcuts that don't use a modifier, or only have one modifier key, are not affected and function as expected
• Replacing the Shift with an ALT modifier (Ctrl+Shift+T -> Ctrl+Alt+T) does not fix the issue
