Probably regression from bug 251786.

@Nitin: can you look at this test here? Maybe it's just a "bad" test to fix as well.
If we cannot find a solution soon enough, we'll need to revert the patch for bug 251786 before M3 (next week).

(In reply to Mickael Istria from comment #2)
The test looks like it's doing something important--or at least it's a valid case to not have a content description there. Please revert the change.

Faulty patch was reverted
