I'm encountering a problem, and I'm not quite sure if it's the same as this, but it seems like it might be related. I've noticed in the past couple of days that FlyerTalk will sometimes load a page seemingly normally, and then at the last minute, just as the page finishes loading, the blue banner at the top will disappear, and all the text will reduce in size. It doesn't happen on every page, so my assumption is that it is somehow related to the particular adverts being displayed - I can't say for sure, though.

I've been able to reproduce this issue in both Firefox and Chrome:

and, for reference, a "good" page in Firefox:

I don't use any sort of ad blocking software or other Firefox add-ons that may be modifying the page (indeed, it happens in Chrome too), and my page style and zoom settings are set to the default.

Any ideas what's going on here?
