De fault code highlight inconsistent with numeric vectors

[MichelNivard]

The default (I think I dint change anything!) numeric vector is inconsistentyl highlighted in positorn (see screenshot).

I didnt want to make an issue beacuse whiel I couldnt fine one, seems like something that ppl have noticed. Is this intentional?

I believe this is the same as #5398. Want to take a look and see if you have anything additional to add?
