Add a couple of reduced test-cases for PR 4259

[Snuffleupagus]

PR #4259 fixed a large number of font bugs, but none of those where added as test-cases. This was, in my opinion, unfortunate since it increases the risk of regressions in the future when other font bugs are fixed.
This PR simply adds a few more test-cases, to improve our test coverage somewhat.

The failures are because of a Firefox update (see #3891). This PR is good to go, so making new references here will also fix the update differences.
