Comment (by SergeyBiryukov):

 Replying to [comment:3 jrf]:
 > Is there anything we could do unit test-wise to safeguard this ? I
 haven't looked at the code in detail (on my break), but I fear this may be
 difficult due to it being part of the global page generation code ?

 Yeah, it's not immediately clear to me how to write a test case for this.
 We can follow up later if anyone comes up with an idea :)
