Outcome

What did you expect?

That the index shown to the left of each list item in the ordered list show it's number in full, including numbers over 100.

What happened instead?

After crossing to 3 digits, the ordered list no longer shows the full index anymore.

Entries 94 to 102:

Entries 194 to 202:

Operating system

Debian (Linux) and Tuxedo OS (Linux)

Application version

Element version: 1.11.81 Crypto version: Rust SDK 0.7.2 (7a21514), Vodozemac 0.7.0

How did you install the app?

https://element.io/get-started

Homeserver

one.ems.host

Will you send logs?

No

Investigation

A possible cause is that the library you use to render the Markdown does left-padding: 2em on ordered list, which is not enough space to hold 3 digits.
