WAR add-ons: editing the add-on description always results in a blank description (only tested with English)

[Zomega-WAR]

On the page for an individual add-on, the description for that add-on can be edited. However, whenever I try to edit the English description, the end result is a bank description regardless of what I put in the edit box. This happens with new add-ons as well as editing existing descriptions.

Examples:

1. https://tools.idrinth.de/addons/dye/ - I managed to wipe out the description when trying to amend it and now it's blank
2. https://tools.idrinth.de/addons/automark/ - new add-on with blank description, unable to set it to anything. It always remains blank.
