Brightspace CSS stylesheet randomly added to source code on our template pages
We have templates available via Public Files for our instructors to use, but recently we have noticed that sometimes a line of code gets added randomly and it messes up our own CSS.<link rel="stylesheet" href="https://templates.lcs.brightspace.com/lib/assets/css/styles.min.css">
This code keeps appearing underneath our own CSS link tags and right before the closing head tag, which means it takes precedence and the styles from this file are being applied to our pages. We have not purchased Creator+ but it seems like this may be the stylesheet for it.
It mostly seems to happen when template pages in Content have been copied from a previous course and then are edited using the source code editor in the new course. Or when choosing Create a File, Select a Document Template, Browse for a Template and choosing the copied template page - then the extra code gets added immediately without even opening the source code editor. (Adding the copied page using Add from Manage Files does not insert the code.)
A separate but possibly related issue: The WYSIWYG editor also seems to have a bug that prevents it from reading any CSS after editing the source code on these template pages, even when the Brightspace stylesheet code does not get added to the source code. The preview is wrong but the page formats correctly when clicking Save and Close.
Why is the Brightspace editor randomly adding code to our pages and how can we stop it? Has anyone else noticed this?
