Suppose I have a code block like this contrived pseudocode:
```Here { is}my code```
When I select the whole block including the backticks and then use try to blockquote it using the button or Ctrl+Q, the block collapses into this:
> ``` Here { is }> > my code ```
I expect blockquoting to preserve each line of code like this (and to make sure the triple backticks are on their own lines):
> ```> Here {> is> }> > my code> ```
Note that blockquotes work correctly with code blocks that use indenting instead of backticks:
> Here {> is> }> > my code
