Markdown undesirable formatting behaviour when new text added to paragraph

[ncasdpo]

In a markdown file, if you have written out a new single line of text, the lorem ipsum paragraph in the recorded example, the formatting is fine.

But when you add text into the middle of the paragraph, the line breaks from the initial formatting will be kept instead of reformatting the whole paragraph again. Please see the screen recording here:

Can follow the issue template?

Hi @sosukesuzuki. Sorry about that, I did try to use the playground to reproduce the error, but I couldn't see how to format the file. I don't know if the formatting is supposed to happen automatically? I pasted in some dummy text and I set the print width to 60 but nothing happened. I have attached a screenshot showing this.
