[1.x] Backport #3920

[DavideIadeluca]

Current Behavior

See the original issue at flarum/issue-archive#39 and fix for the 2.x branch at #3920. IMO it's a major enough issue that it warrants a back port. However, especially if backwards compatibility is of concern, I understand if we don't want to port this.
