SEB 3.7.0: Clipboard Policy: SEB Only - Copy-Paste issue

[AntonT76]

Hi,
I have found a strange issue with SEB 3.7.0.682 together with the new clipboard policy (SEB Only). We try to allow students so copy & paste some text from other websites in Moodle essay question type. Maybe it is similar to the issue #890

Describe the Bug
We changed SEB configuration:

• tab "Security"
• Clipboard Policy
• Set "SEB Only" to true
  and we also allow students to open a new SEB Window (in this case: https://onecompiler.com/).

Students are able to copy content, but

• only the first line of code instead of the whole code will be copied
• text content will be copied without formating
  Please see screenshots an log files below.

If I set "Clipboard Policy - Allow" to true, there is no problem with copy/paste (see screenshots and log files below)

Steps to Reproduce
Steps to reproduce the behavior - Setting 1 SEB Only:

1. create a SEB Config file (set "Clipboard Policy - SEB Only" to true, allow additional websites)
2. create a test with some essay questions and links to additional website
3. start SEB, start quiz, go to essay question, click on the link
4. website will be opened in an additional SEB window
5. mark all the code, copy it into essay question (STRG-C + STRG-V) --> only the first line will be copied
6. go to an other website, try to copy some text (STRG-C + STRG-V) --> whole text will be copied, but no formating

Steps to reproduce the behavior - Setting 2 Allow:

1. create a SEB Config file (set "Clipboard Policy - Allow" to true, allow additional websites)
2. create a test with some essay questions and links to additional website
3. start SEB, start quiz, go to essay question, click on the link
4. website will be opened in an additional SEB window
5. mark all the code, copy it into essay question (STRG-C + STRG-V) --> all line will be copied
6. go to an other website, try to copy some text (STRG-C + STRG-V) --> whole text with formating will be copied

Expected Behavior
If I mark all the content, the whole content should be copied including formating options.

Thanks for the extensive report. This might well be a limitation of the current implementation, as we at the moment only share the raw text content between windows. We will investigate whether we can improve this in an upcoming version.
