When creating an assessment, disconnect between typed content and preview tab

[pbarry-r7]

Describe the bug
I had started an assessment, checked the markdown "preview" of it, then closed my laptop, returned later, modified my assessment content, but when I clicked preview again, it showed my old content. Short video clip under "Screenshots" below (wouldn't let me attach the raw video file, but would let me attach it as a ZIP).

To Reproduce
Steps to reproduce the behavior:

1. start an assessment on a topic, type some words in there
2. click the preview tab
3. put laptop to sleep or maybe just go away for a long time
4. return later, modify text in assessment
5. click preview tab and old text remains
