Because @askvortsov is not available for any release right now, I forked this project and released some patches today.
composer require glowingblue/flarum-rich-text:v2.0.4-beta.1
This is released under the
glwowingblue namespace, as @glowingblue is sponsoring this update!
Once my changes / fixes will be merged in the official repository, the glowinglbue fork will be deleted.
beta tag is only used here so that the official repository can later release a
v2.0.4 without interfering with this fork.
