LTI embeds in rce content lose all their url parameters when editing content after saving the page


This behavior has been resolved and deployed to the production environment as of 2/28/23


When you edit a piece of RCE content and embed an lti launch in it, revisiting the edit page after saving it strips all of the url parameters from the src=/courses/961/external_tools/retrieve url that is used to provide the context of the launch itself.

Expected Behavior

To have it load the url parameter 


No workaround exists at this time.

Steps to Reproduce

View the page below and see it has an lti embed saved in it and the video works fine, but then edit it and see the preview in the rce no longer works.
