[v8] WYSIWYG Code View error

I’m using v8. The new wysiwyg is awesome, but it has a big error now. When I try to enter html tags in the View Code Mode, it automatically encodes the tags
For example: < h1 > turns to & l t ; h1 & g t ;
Issue number 2: I cannot type Tab to indent my text
Please take a look at this screenshot

Thanks for reading

Please make a github issue.
