The nightly builds seem to be adding extra <p> tags when toggling between source view and markup, and then converts all markup to html entity codes.
1. Visit http://ckeditor.com/demo
2. Click the "Source" button once.
3. Click the "Source" button again.
This does not happen with Safari 5.0.3 6533.19.4
I see similar oddities with the TinyMCE editor as well when viewing the HTML source and using it's Cleanup Messy Code function. Works fine in Safari, but not in Webkit.
The problem with both editors begins between Nightly r72487 and r72783.
It also affects PPC 10.5.8.
Just posting to indicate that this problem is still around.
Confirmed on nightly r79746. This might be a duplicate of https://bugs.webkit.org/show_bug.cgi?id=54978.
This indeed was a duplicate of 54978. The bug no longer reproduces on the nightly r80210.
