There are other usecases that create similar fatal IDE errors:

Steps:

1. ASSERT: have a cluster where you have at least 2 pods
2. EXEC: describe the 1st pod (dont close the editor!)
3. EXEC: describe the 2nd pod (dont close the editor!)
4. EXEC: describe the 1st pod again

Result
A Fatal IDE error is displayed with the same stacktrace as above and the following error is displayed:

Expected
The 1st editor is focused, no errors are displayed.
