Description

When opening the Articles & World Manager button on the left toolbar, it opens a window with red text stating "Object.hasOwn is not a function" instead of the article tree.

It showed up on a pre-existing world and a new world created after seeing the error.

A hard refresh didn't change anything and the browser was just installed.

Steps to Reproduce

Log Into Account

Click on Articles & World Management tab on left sidebar

Error appears on opened tab

Hi, this is because you are using an old version of your browser which doesn't support some newer features - please update it to a newer version and this should resolve the issue!
