Reflow breaks markdown links

[jkaye2012]

Hey there,

I found some surprising behavior today. I feel like this must be known already, but I wasn't able to find an issue for it, so apologies in advance if this is a duplicate.

The reflow command seems to not respect Markdown links; specifically, it seems like a ]( pair isn't recognized as a token that shouldn't be broken when reflowing. The problem is triggered specifically when the link text is within the line length, but the link
itself is beyond the length. For example:

This is a line that isn't that long [with a link in it](https://google.com).

If the line length is set to 55, this will be reflowed to:

This is a line that isn't that long [with a link in it]
(https://google.com).

which breaks the link. Is this intended?
