These tests were failing on HHVM because of the default 3 second timeout.
Yes, HHVM is supposed to be faster, but there's a "warmup" time for scripts
in JIT mode (which is on by default). I suspect that's why they're failing.

It has no effect anyway and in case we would want to make syntax
highlighting optional, it needs to be done in javascript and needs
better configuration name than this one.
