User get popup "WARNING: _editor_irl is not set!" when opening a KB article using htmlarea - Known Error

User get popup "WARNING: _editor_irl is not set!" when opening a KB article using htmlarea Description When using "htmlarea" instead of "TinyMCE" and opening a knowledge base article we get a pop up error message

"WARNING: _editor_url is not set! You should set this variable to the editor files path; it should preferably be an absolute path, like in '/htmlarea', but it can be relative if you prefer. Further we will try to load the editor files correctly but we'll probably fail."

Steps to Reproduce

Set system property - **glide.ui.html.editor** sets to htmlarea Open any KB Articles. Expected - KB Article should be opened

Actual - Instead of opening KB Article, it shows following pop-up.

Workaround The TinyMCE editor is the editor of choice. We recommend all users switch to that editor for the best experience.
