org-context is ancient. It relies on org-links being fontified using
'org-link face and would fail for any non-standard link with :face link
parameter. Moreover, the return value will be different depending on
org-link-descriptive setting.

We should probably deprecate this function and encourage using
org-element-context. So, I recommend rewriting your code with
org-element-context.

It seems that some of the faces were not applied together, making
next-single-property change stop early because faces are not 'eq (though
'equal). Not sure if we really need to do anything about it. It is a bad
idea to rely on next/prev-property-change in org-context anyway.
