LO 1:6.0.6-0ubuntu0.18.04.1 in Bionic is likewise affected, and the workaround also works here.

Amended to replace whitespaces mixed with tabs in extension.json, and to fix description message id.

Refactor file structure so that the extension can be loaded using MW 1.25+ style wfLoadExtension(), and makes MW 1.25+ a requirement. Otherwise the core functionality should remain just as it was (i.e., if it doesn’t, that’s unintentional on my part).

This closes issue #3.

Since MediaWiki 1.25, the suggested method of registering extensions has been to use wfLoadExtension() instead of a direct require_once. AddBodyClass currently (v1.2.0 from 2016-03-21) still uses the old style, so I’m opening this issue to suggest converting the extension to use the new method.

I’m also preparing a pull request with the minimal changes that I think should accomplish this, and I’ll post it next.

This happens in 18.04 too. Bug #1650076 does also, and I’m not 100 % sure if these are two different issues or the same. I was able to reproduce #1650076 with the steps listed there, but just before that I had Evince following my scroll wheel despite being unfocussed, and I had not selected anything in the PDF before that (at least not knowingly). I haven’t found the steps to reproduce this without the selection though.
