Cannot disable Eclipse switching to TITAN Execution perspective

Summary

I was trying to run my projects keeping Eclipse in the TITAN Editing perspective.

Steps and/or TTCN-3 code to reproduce

Install TITAN with Cygwin and the eclipse plugins on a Windows machine. Take any compilable TTCN-3 code, then create a cfg file. Then under Window > Preferences > Run/Debug > Perspectives select Never under "Open associated perspective when launching", and Never under "Open associated perspective when application suspends". Also, under Application Types/Launchers, select each element beginning with TITAN, and under Modes/Perspectives, select TITAN Editing. Then click Apply&Close, and restart Eclipse.

Eclipse version used: Version: 2021-12 (4.22)

What is the current bug behavior?

When I click on the cfg file then Run as > TITAN Parallel Launcher, it switches to the execution perspective, despite the above config steps.

What is the expected correct behavior?

Eclipse remains in the TITAN Editing perspective.
