[#1]

This behavior has been resolved and deployed to the production environment as of 3/26/25

Description

When a course contains a page with between 400 and 10,000 nested html tags, the course can be exported successfully, but attempting to import the export package or copy the course into another course the import fails with aDocument tree depth limit exceeded error

Expected Behavior

Instead courses which can be exported successfully should import or copy successfully as well.

Workaround

No workaround exists at this time.

Steps to Reproduce

Prerequisites: Two courses, one containing a page with 401 nested html tags.

1. Export the course with the page.

2. Attempt to import the export package in the other course and note that the import fails and an error report with a Document tree depth limit exceeded error is produced.

3. Attempt to do a course copy from the course with the page into the other course and note that the copy fails with an error report with the same error as above.
