Embed a large enough number of Telegram messages on a page in Telegraph (the site, not the Graph Messenger), open that page in Mozilla Firefox 86 (a screenshot of https://telegra.ph/MSiH-02-14 is attached here as an example), and then suddenly most of the embedded messages have problems of inufficient height and thus their bottoms are cut and not visible on the page. Only the first four lines of text are visible.
(The browser's user might then try helplessly clicking on Telegram's logo in the top right corner of such embeds… but that logo's URL leads to https://core.telegram.org/widgets instead of the message's source.)
Some messages have sufficient height and thus either a race condition or an execution limit might be suspected as a reason for some embeds to look fine at the expense of all the others.
If this problem can be reliably reproduced by the developers, then I hope that the appearance of Telegram messages on Telegraph pages might eventually be improved for Mozilla Firefox.
