Hello! I just added this to my Chrome, and first thing I want to say is thank you SO much for making this! This is a wonderful idea!
But sadly, I'm having that same issue as a few others in here ='( When copying from my microsoft Word, a lot of the spaces between words goes missing, although the italics are staying.
However! When I copy the same text from Google Docs, the spaces don't go missing (and the italics are staying) so that works like a charm =D
