The number and then the dot at the beginning of the Rocket.Chat message are treated by Showdown as an ordered list

[drygdryg]

Rocket.Chat messages containing a number and then a dot are treated by Showdown as an ordered list, this leads to incorrect display of large numbers and inability to read them.
For example, the message

12345678. There's a problem with this personal ID.

Showdown converts to:

<ol start="12345678">
<li>There's a problem with this personal ID.</li>
</ol>

Together with the problems with displaying ordered lists in the Element Desktop client, we get an unreadable number, which is cropped on the left :

Reading the Showdown documentation and examining the Issues in their repository yielded no results. Maybe someone has any ideas on how to solve this problem?
