Horizontal rule vs. simple table: Is this expected behavior?

[bartonc-javs]

I was working on a document that used horizontal rules; i.e. - - - at the beginning of the line.

If I put a newline after the first horizontal rule, everything rendered correctly:

- - -

## ASDF ASDF

- - -

... but I accidentally left this off:

- - -    
## ASDF ASDF

- - -

... and it suddenly rendered as a very weirdly formatted table.

The thing that made it extra confusing was that I had an unordered list with GFM checkboxes. If there was more than one level in the checklist, it rendered as an unordered list

- - -    
## ASDF ASDF

* [ ] This doesn't render as a table
    * [ ] qua qua qua 
- - -

But when I removed the second level of list items, it turned into a table

- - -    
## ASDF ASDF

* [ ] This renders as a table
- - -

This made it feel like a problem with the ordered list rather than a horizontal rule not followed by an empty line.

I'm trying to decide whether to open a bug report on this. It may conform to a design spec, but it certainly didn't feel like a common sense rendering when it happened (especially because I usually use pipe tables)

It's technically a (malformed) simple table (see the docs).
(Of course you can turn these off if you don't use them; indeed, with -f gfm they will be turned off.)

Perfect, thanks!
