Not at all, you’re simply not running the TL 2014 version. I just
checked with the beta, and you are of course correct. Looks like
this was fixed in Context since. Not in the plain fontloader,
though.

Which allows us to bisect =) Turns out the matter was fixed in
Context *very* recently. I traced it to a change from last week.
On my Context mirror it corresponds to commit
606f30879286f37c0cf0ef42bc225e835d0d596d:

    https://bitbucket.org/phg/context-mirror/commits/606f30879286f37c0cf0ef42bc225e835d0d596d

-- which is, unfortunately, is quite a huge changeset. I’ll
investigate.

Best,
Philipp
