Horizontal rules breaking parsing

Zecc

Correct behaviour

Markup:

So what *should* you do?
**Party!**
[link](http://example.net)
`Some inline code`

Result:

So what should you do?
Party!
link
Some inline code

Incorrect behaviour (simply added <hr> before)

#### Markup:

<hr>
So what *should* you do? **Party!**
[link](http://example.net)
`Some inline code`

Result:

So what *should* you do? **Party!** [link](http://example.net) `Some inline code`

Note

This bug doesn't manifest if you replace <hr> with other tags (tested with <a>, <blockquote>, <pre>, <q>, <div>).

Adding two line breaks after the <hr> also prevents the bug.

The bug also doesn't happen if the <hr> is within a BBcode tag:

####Markup:

@Some Guy said:<blockquote><hr>
This is a text.
[This is a link](www.thedailywtf.com)</blockquote>

####Result:

@Some Guy said:

This is a text.
This is a link

Reported to discoursebugs.com:

Edit: you'll have to excuse the bad formatting in that bug report. Looks like bitbucket doesn't like blockquotes. Also there is no such bug over there either.

Also, thanks @Matches for volunteering to create an actual bugtracker. Hope you haven't regretted it much.

Oh god, this is just outright insane:

####Markup:

<hr />
This is a text.
[This is a link](www.thedailywtf.com)

####Result:

This is a text. [This is a link](www.thedailywtf.com)

vs.

####Markup:

<hr/>
This is a text.
[This is a link](www.thedailywtf.com)

####Result:

This is a text. [This is a link](www.thedailywtf.com)

Yes, adding a space inside an <hr/> breaks links.

BBCode also fixes XHTML tags:

####Markup:

@Some Guy said:<blockquote><hr />
This is a text.
[This is a link](www.thedailywtf.com)</blockquote>

####Result:

@Some Guy said:

This is a text.
This is a link

It's apparently an interesting edge case.

B-but that still doesn't explain the total and utter WTFERY that their XHTML parsing is.

I'm not quite convinced that either of the words "XHTML" or "parsing" apply in this context.

I've been surrounding reports in code backticks, seems to work reasonably well in most cases. I haven't been able to handle these in a few days, I'll get back to it soon but I'm trying to close a deal at work.

Before someone gets pedantic on me, I realize (simply added <hr> before) is a lie: there is a missing line break before **Party!**. Doesn't affect the bug however.
