Container: copy/pasting some content directly in source mode in main content breaks the platform

[nino-filigran]

Description

In a container, when turning the main content into source mode & copy pasting some text, the platform breaks

Environment

demo octi

Reproducible Steps

Steps to create the smallest reproducible scenario:

1. go in a report
2. switch main content into source
3. copy/paste some text
4. platform hangs & breaks (page become unresponsive, impossible to do anything)

Happens also when copy/pasting some text as source in Data/customization of the content

Expected Output

Like the UI mode, I expect that the platform is able to copy/paste in source mode without breaking

Actual Output

Platform hangs & breaks (need to close the tab)

Basically, this behavior happens each time you're in source mode, anywhere on the platform
