Embedding multiple posts will load only one post in all embeds

[trwnh]

Steps to reproduce the problem

1. Copy the embed links for multiple different statuses
2. Paste the iframes into a web page
3. Load that web page

Expected behaviour

The different posts load in their respective frames

Actual behaviour

Only one post will load in all frames

Specifications

mastodon.social -- have some screenshots

this seems to be some kind of caching bug, as removing the iframes and trying to load only one at a time still causes the first-loaded one to be shown instead.

specifically in the javascript, as disabling javascript makes the correct posts show (although they are the wrong height, of course)

Hm it works for me, including embedded posts with media.
Works for me in Chromium, Falkon, Firefox and Vivaldi.

Maybe if it helps to track this down, I am on Arch Linux with:
chromium 96.0.4664.110-1
falkon 3.1.0-16
firefox 95.0.1-1
vivaldi 5.0.2497.32-1

Tested embedding in a simple page using:
$ php -S localhost:9000

and on a live page.

Including the script multiple times may cause needless message-passing between the frames, but I fail to see anything that would cause this behavior, it only changes the frame's height…
