Detached script/editor not obeying file menu commands

#### System information:
- Win 10 Enterprise (64) 21H2
- 22.1.2.202207091909

#### Describe the problem you're observing:
When a detached script window is active, file commands from the menu are done on the last active attached script, which is obviously not ideal.
#### Steps to reproduce, if exist:
Open two scripts, detach one of them. Make sure the detached script is the 'active window', go to the file menu and save as 'test'.. You will find that the file saved is the attached script, not the detached one.
