Empty preview, various errors in devtools

[CherryDT]

I've just installed this extension and it looked great in the store, but it doesn't seem to work.

However, in the status bar I can see a number of rows:

In the devtools there are various errors:

EDIT: While I was playing around, I got it to work once. I tried maybe 50 times or so, but it worked only once!

EDIT2: I just discovered #250, somehow missed that at first. Yes, light theme fixes it for me too. Should my issue be closed? I'm not sure if it's all the same because the errors appear to be different...
