Mac spelling correctness doesn't work - "addRange(): The given range isn't in document."

Hi,

When I paste text from outer source into the text editor and trying to fix spelling, the word is getting deleted (see attached video).
In addition, the warning "addRange(): The given range isn't in document." is printed to the console.

How to reproduce:

1. Copy from gmail some text with spelling error. for example: "hre are th msitaks".
2. Past it into the text editor and try to fix spelling using mac spelling checker (right click).
