Editor's style buttons (and corresponding hotkeys) don't always result in valid Markdown

[brie]

As pointed out by @levicki, the editor's application of bold/italic/other styles (per hotkey or clicking one of the style buttons) does not properly handle a selection that crosses boundaries between paragraphs.

For example, when selecting [some\n\ntext] as shown below, and then clicking the B button for bold text:

this is [some

text] that crosses two paragraphs

The expected result is that the selection becomes bold, which requires this Markdown:

this is **some** **text** that crosses two paragraphs

this is some text that crosses two paragraphs

But the actual result is that the style is broken:

this is **some text** that crosses two paragraphs

this is **some text** that crosses two paragraphs

Yes, it's been documented before **don't worry **bolded text

I'm sure that a PR to fix this would have a good chance of being accepted.
