Spaces removed on pasting

[oaknorton]

Describe the bug
I'm copy/pasting text into a SunEditor window and it removes spaces in the text.

To Reproduce
Steps to reproduce the behavior:

1. Go to: https://veritypublishing.com/resource?id=MjU2&show=0&para=1
2. Copy the last line of the first paragraph
3. Paste it into a SunEditor window
4. Notice how it inserts a leading line break and then removes spaces in "taught somewhat in all the" so it appears as "taughtsomewhatinallthe"

Expected behavior
It shouldn't insert a leading space or remove spaces

Happens to me too. It's enough to copy paste back to back formatted words from suneditor itself.
