Shortcuts don't work for new files in the Editor

[gepcel]

What steps reproduce the problem?

1. After opening spyder, a default script file probably named untitled0.py is created, shortcuts like run selection and advance or create_new_cell work perfectly.
2. After closing the current file (only the file, not spyder), spyder will automatically create another new script file probably named untitled1.py, shortcuts like run selection and advance or create_new_cell stop working.
3. The toolbar button Run selection or current line stops working either.

Update:

Minimize the window, maximize it again, the shortcut works again.

Versions:

• Spyder version: 6.0.2 (conda)
• Python version: 3.9.15 64-bit
• Qt version: 5.15.2
• PyQt5 version: 5.15.11
• Operating System: Windows-10-10.0.19045-SP0

Note: If this is not reproducible, although I'm using spyder 6.02, but I merge the #23024 manually.

Hey @gepcel, thanks for applying #23024 and reporting this problem. I was able to easily reproduce this, so we'll fix it before 6.0.3 is released.
