This happens because their variation tables are dropped by the font sanitizer, due to minor spec deviations in the MVAR table.

Analysis shows the issues to be harmless, and the sanitizer can be relaxed to allow these fonts to load as expected.

Submitted https://github.com/khaledhosny/ots/pull/169 upstream; when this is merged, we can pull an OTS update and the issue here will be resolved.
In particular, this fixes the validation of a couple of example variation fonts seen in the wild.
