(Bug report) Automatic list continuation has overly aggressive pattern detection

[IrtaMan]

Steps to reproduce:

1. Open any form that uses the markdown editor
2. Type 1x (the number 1 followed by the letter x and a space)
3. Press Enter to create a new line

Expected result
The cursor should move to a new line without any automatic text insertion. The user should have full control over what is typed on the new line.

Actual result
The markdown editor automatically inserts 2. (the next number in the sequence followed by a period) on the new line, treating 1x as the start of an ordered list.

Is this a bug or expected behavior? Thanks!
