Extra whitespace and line breaks being inserted on paste in Windows.

**Describe the bug**

Extra whitespace and line breaks being inserted on paste in Windows. It's a new line in front, and 2 new lines afterwards. It doesn't matter if I'm copying from the middle of the line, or the middle of a _word_, any paste creates the extra space.

**To Reproduce**

1. Use Windows
2. Use a `markdown` widget.
3. Attempt to copy-paste text into the widget.
4. Note the extra line breaks.

**Expected behavior**

It should paste the text as expected, only adding new lines if they were copied.
