I think this might be the exact same issue as #61111.

Where we only look for seters with that name. But I'd keep this open until we can take a look at that one.

Just to be explicit, which identifier(s) were you expecting here? The snippet is long, and I could not find anything that contained those characters together. Can you try completion in the other line for a screenshot? Thanks!

[scheglov]

I expected baseCollection.
Yeah, it looks very much like #61111, slight difference that here we at the start, and there in the middle.
But I suspect that you are right, and it is related to being inside assignments and looking for setters.
