ID 590814 - Node Graph shortcuts will sometimes apply with the timeline open

Problem summary
When switching from the Node Graph to the timeline in Nuke Studio, sometimes the Node Graph shortcuts (such as 'x' to open the TCL menu) will still work when the timeline is active.

Customer reported version
Nuke 15.0v5

Customer reported platform
macOS 14

Steps to reproduce

1) Launch Nuke Studio.

2) Import some footage and drop it into the timeline.

3) Click the Node Graph tab and click in the Node Graph.

4) Go back to the Sequence tab and press a Node Graph shortcut (e.g. 'x' for the TCL menu, 'b' to create a Blur node or 'm' to create a Merge node).

Expected behaviour
These hotkeys should only work when the Node Graph is open and in focus.

Actual behaviour
The hotkeys retain their Node Graph functionalities, even when the timeline is open and in focus.

Workaround
Unknown.
