Error annotation right-click behaviour not working (Chrome, Firefox)

[iacercalixto]

First of all, thank you for open-sourcing this tool and sharing it with the community.

This issue I am reporting show up when using Chrome and Firefox (with ubuntu).

I have just installed the tool, but the right-clicking behaviour in the error annotation interface does not seem to work as expected. When I select one or more words and right-click to add an error, no window with error options to select from show up. Instead just a thin line appears, and if I left-click again it disappears. I tried with different projects and sentences, the same thing happens every time.

Could there be an easy fix (I am assuming this is just some simple javascript) to this issue, or a workaround? I do not programme in JS, it would probably take me too much time to be able to find out what's going wrong.

Thanks!
