Multiple editor instances inserted for review multiline comment

The integration with inline code comments is quite delicate. GitHub uses pjax in the Pull Request pages and this makes things much harder. The extension disables pjax in a few pages but maybe some are still missing. As disabling pjax is something to be done on the links that open the code review page, the following information is very important. So here it goes my question:

tl;dr - what is the exact path you do to reach the commit page where you see this error?

This happens kind of randomly 😕 Encountered it today, checked few repos and it was happening. The path is just:

1. Go to any repo.
2. Switch to Pull requests tab.
3. Open any PR.
4. Switch to File changes tab.
5. Create multiline comment.

Long story short, I have then detached one Chrome tab to record a gif and it stopped happening 😆

Took a look once again and I start to suspect that it is somehow related to having multiple tabs opened:

It's not really visible on the gif above but after creating first multiline comment I'm opening the second tab with the same repo (different PR) and creating another multiline comment.
