[2.1.9] Train interrupt triggers after upgrade and train is stuck

[Zettroke]

What did you do?

I marked train heading to the station for upgrade. Train has interrupts in it's schedule

What happened?

When train stopped at the station and got upgraded it triggered it's interrupt even though wait condition wasn't fulfilled.
Also when interrupt is triggered this way train doesn't head to destination station.

What did you expect to happen instead? It might be obvious to you, but do it anyway!

Train would wait for it's wait condition before executing interrupts.
When interrupt triggers, then train should actually head to destination station

Does it happen always, once, or sometimes?

I have attached video and save file with complete reproduction

This is probably related to #134254 or #134469, as advised in this message I'm opening new bug report with complete reproduction for similar issue
