When students Paste a screenshot into Online text assignment, they can see the image in the Editing field.
But, after submission, the screenshot picture is NOT saved. When checking the <code>, all Base64 code disappeared.
Then, I checked the permission to Enable trust content in site:
And enable to Student role.
A student role can Paste a screenshot (the same Base64 code image) to forum successfully.
My Question is: Why the student role can paste Screenshot (Base64 code) in Forum, but not in Assignment? If it is a security reason, I think the forum and assignment should be treated as same.
BTW: Teacher and higher role can paste a screenshot and save the page without any problem.
