调研方向
Start with contentcuration/contentcuration/frontend/shared/views/QTIEditor/serialization/xml.js, especially the adoptNode code at lines 99–103, and trace how the prompt reaches TipTap and is serialized back to raw_data. Reproduce the prefixed-MathML case described in the issue, then add an end-to-end test for opening and saving the item. Done means the formula remains MathML in raw_data and the saved item passes the QTI XSD check.

Observed behavior
- A QTI item whose prompt carries MathML under a prefix (
xmlns:mon the root,<m:math>in the prompt) loses the formula on its first save from the editor. Only its text survives. - Source prompt:
<qti-prompt>solve <m:math><m:mi>x</m:mi><m:mo>+</m:mo><m:mn>1</m:mn></m:math>.</qti-prompt> - Saved prompt after typing at the end:
<qti-prompt><p>solve x+1. Edited</p></qti-prompt> adoptNodere-creates foreign elements withcreateElementNS(namespace, node.tagName), so the HTML handed to TipTap contains<m:math>, which TipTap does not recognise as math.
Expected behavior
- The formula in the prompt survives the edit.
User-facing consequences
- Imported items that use prefixed MathML silently lose their formulas the first time anyone edits the question text, and publish without them.
Steps to reproduce
- Seed an exercise with a QTI item whose root declares
xmlns:m="http://www.w3.org/1998/Math/MathML"and whose single-choice prompt contains<m:math>…</m:math>. - Open the exercise's Questions tab, click "Edit" on the item, type at the end of the question text, click "Close".
- Read the saved
raw_data: the<m:math>element is gone.

Acceptance Criteria
- Editing the prompt of an item with
<m:math>(prefixed MathML) saves a prompt that still contains the formula as MathML. - The saved item passes the QTI XSD check.
- A test covers it, from opening the item to the emitted
raw_data.
