This is still happening in this example, although it's only an example. (I've encountered it in many threads over many months - I've only just got around to posting about it!)

Having another play with it using what I posted above, I've discovered something else:

• If I go to https://www.flyertalk.com/forum/34278564-post961.html, the icon works. That URL is what is in the address bar, so there is no page number in the URL.
• But if I go to https://www.flyertalk.com/forum/british-airways-executive-club/1653179-best-t3-oneworld-lounge-25.html#post34278534, then the behaviour is still exactly the same as before.

That rather strengthens my suspicion that the problem is linked in some way to changing pages to get to the post being asked for. (I've deactivated the URLs above so that there's no automatic parsing by the FT software.)
