markdown-mode doesn't render maths as expected when killing and undoing. #352

Open PhoenixStarEclipse opened 6 years ago

PhoenixStarEclipse commented 6 years ago

Expected Behavior

Markdown-mode should render maths properly when killing and undoing.

Actual Behavior

Kill and undo-kill upper multiline equations, and lower multiline equations will get unhighlighted.

Steps to Reproduce

  1. type 
    
$$a
b$$

$$c d$$

and make sure that there's an empty line between the two equations.
2. Kill lines `$$a` and `b$$`.
3. Undo the two kills by pressing C-/.
4.

$$a b$$


gets and remains unhighlighted.

$a$b$c$

I have merged #487. I suppose https://github.com/jrblevin/markdown-mode/issues/352#issuecomment-409826496 issue is fixed. Please check latest version.

I suppose this issue is emacs problem, not markdown-mode.
