Hi,

I came across a situation where I had an org link inside a figure caption.

But the way the org-set-font-lock-defaults is written, the org-link face
gets overridden by org-meta-line face because the meta line fontification
is done AFTER link fontification.

Is there a specific reason why the meta line fontification has to be done
at the very last?

I have edited this function (just moved the meta line fontification above
link fontification) and now I can see a link fontification within the
caption.

I would like to understand if there is a reason why one should not move
this order.

Thanks!
