Odd behaviour with colon, emphasis and linebreak

When trying to render the following markdown, the emphasis is not rendered correctly:

next line

When the break is done with 2 spaces, it renders correctly.

I think this is the same issue as discussed in

Hi @Crissov,

Yes, you’re totally right. I did not use the right search terms when looking for existing items :slight_smile:

Funny thing is that commonmark.js renders correctly without the colon, but wrong when a colon is being used.
