Avoid new record submission to trigger reload of record data via contextual sidepanel

[Vegard S]

Not sure how to explain this, but my issue is the following. 
On the record page of Service Operations Workspace I've added a contextual sidepanel. 

This sidepanel contains a form which displays data from a related record. 
I can update this record just fine by using the save event of the record controller. 
I did notice that whenever the new form controller loads it's data it refreshes the title of the page and the main tab. Interfering with the original record I actually have opened. I managed to get around this by manually updating the title using helpers.screen.updateStatus.

So far so good...
But when the sysId is -1, aka a new record, it submits and reloads the whole thing, including the url and everything. 

I just need it to save the record and stay where it was without refreshing anything. 
So far I've been looking into several options, such as trigging a UI Action which includes current.insert(), but the current is this context is the new record, and I have no reference to the original record I'm actually on.

I've also looked at binding a script to the Form Controllers Form status changed event. 
And in that event I can see that event.payload.status == 'inserted' and maybe via that I can abort everything else. 

Does anyone have any ideas?
I know I could run my own Data Broker Transform script, but I need the validation of the form to make sure mandatory fields are taken care of. And the form has all the data necessary, I just want to abort all additional actions after the record is inserted.
