Markup error: diff code block

[eki3z]

Expected Behavior

```diff
- plugins=(...)
+ plugins=(... fzf-collection)

When enable hide markup, the code block shouldn't be changed:

- plugins=(...)
+ plugins=(... fzf-collection)

Actual Behavior

• plugins=(...)

• plugins=(... fzf-collection)

Steps to Reproduce

1. emacs -Q
2. (markdown-mode 1)
3. (markdown-toggle-markup-hiding)
