Recently I have repeatedly encountered a bug with the Markdown code block button. I’d usually select some block of code and click the button to make it indent by 4 characters and everything works.

Except that sometimes, a somewhat random string is added to the first line (the string always appears to be some parts of CSS).

Right now I can reproduce this only with the text visible being added in front of the line, but I did have different and also more broken text lines in the past. If I encounter any other later, I’ll add those as well. Anyway, here is an example where I just typed Foo bar, selected the line and clicked the button:

    When copying and pasting with Chrome, sometimes Chrome inserts non-breaking space characters at the start and indentation fails. Fix: manually backspace and reindent. Mar 21, 2013 at 18:03
  • I use Firefox, and I typed the Foo bar. Also, the indentation works fine, there is just some new extra text…
