I can not reproduce all the things you report.
I think part of the problem is [calc:]. I have to have at least two
characters of path to get a link that is colored.

I get partial chartreuse, but there are some fontlock that can go on
top, e.g. if it looks like a latex fragment.

I can reproduce the issue above, but I have no way to help improve it.
This particular case looks like emphasis from a simple regexp pov.
Fixing it might require checking that the start/end are in the
same org-element maybe.
