A bug with breadcrumbs and R sections?

[SamT123]

Hi!

I think there may be a bug with breadcrumbs when using comment-defined sections in R (i.e. "# title ------") – but want to check here before opening an issue.

When not using comment-defined sections, breadcrumbs.focus starts with the "highlighting" focussed on the part of the code you are currently in, which is very useful for navigation:

i.e. if I do breadcrumbs.focus when my cursor is here, in my_fun_2.2:

breadcrumbs starts with my_fun_2.2 highlighted, and I can navigate from there with the arrow keys:

But, if there is are comment-defined sections above it, breadcrumbs seemingly doesn't know where I am in the code:

EDIT:

The hierarchy / structure of the document in breadcrumbs is correct, its just that the highlighting doesn't start in the right place. Here I've have expanded out the folded sections:
