This fails only on late beta.

Ting-Yu, can you please take a look at this?

Oh, I didn't aware that layout.css.contain.enabled is still disable on late beta and release. The two tests require the preference. I'll upload a patch to fix this.

CSS containment is enabled on early beta or earlier. Using
"default-preferences" to flip column-span pref overrides CSS
containment's pref at the first line in the reftest.list, which make the
two test fail on late beta.
