Right panel name truncation

I’ve come across something that I can’t understand and would love to get some insights as to why this could be happening.

So I’m trying to organise nested components and name them in a way that makes sense to how they appear contextually when being used.

I’ve noticed that for some reason, the titles on the right hand panel have a very unusual pattern of truncation.

Here are some examples:

As you can see, the truncation is not based on the length of the word. I’ve tried different combinations as I’ve shown above and I think the pattern is that if it is more than one word (separated by a space) it truncates, which seems very odd to me.

Is this intended behaviour or is it a bug?

Actually I realised that the pattern of truncate if there are spaces is not the case either, as I’ve tried multiple spaces and that doesn’t seem to truncate the names. Super unusual.
