Comment 6 for bug 1927870

The this.recordSource never does get set anywhere, so that part of the ngOnInit doesn't really do anything.

Now I think this issue is that the fromId() function completes before the bib source data loads, and that is where the source from the current record gets applied to the sourceSelector combobox.

So maybe fromID just needs to set a value for this.recordSource as well as trying to update the combobox directly. That way if the combobox data gets loaded later, it will set the correct source.

I'll give it a try.
