editor sees syntax child [type="suffix"] Box {} as broken

[djkato]

I'm not sure if this is the way, I got the answer from an LLM, as I couldn't find the answer to this through googling.
I wanted to achieve what is mentioned here:

The AdwActionRow implementation of the GtkBuildable interface supports adding a child at its end by specifying “suffix” or omitting the “type” attribute of a element.

But I couldn't find a way, besides what I got from LLM.
While the LSP seems to be comlaining, GTK does render it correctly, so it probably is the right syntax I think?

if I'm having a skill isue lemme know. I picked up GTK4 this week and still learning :)

Hmm actually it seems it might be just ignoring that part and continuing as if it wasn't child: but just regular child? so it seems correct but actually might not be.
