Prettier formats 3-level bullet list with no content to thematic break

[xiaq]

Prettier 2.7.1
Playground link

Input:

This is a 3-level bullet list with no content:

- - *

Output:

This is a thematic break:

- - -

Expected behavior:

Don't format - - * to - - -.

In general, for any N-level bullet list with no content, avoid using 3 consecutive -s. This can be done by alternating with * or +, as is done in the input.

Found another similar case:

* --

Prettier formats this to:

- --

Which is again parsed as a thematic break.

Thanks for reporting this bug @xiaq 👍 Interesting edge case indeed!
