Sorry for the late reply.
We're using v13.0.115.
For the second issue, to reproduce:
- In a rich text widget click the 'Code View' button
- Make a change in the code
- Click 'Save'.
- The page reloads and the changes made in the code are not applied (or saved).
If you make the change and switch back to the WYSIWIG mode, the changes will be saved. It appears to be any change, even a character changing in a paragraph, so appears to be a bug rather than a HTML sanitization feature.
For the changing of links in the code view, is there a way to turn off this off? I'm guessing not, but thought I'd ask.
