The node preview has a protection built in that shows a dialog and prevents navigation when any link in the preview is clicked. Currently, this protection is applied to all links in $(document), which isn't a problem in the normal node preview since it is opened in a new page. The
Same Page Preview module →
however opens the node preview in an iframe, which causes this link protection to be applied to the previewed page as well as the node edit form.
Scope adding the link protection to links in $(context) instead of in $(document). Without same page preview enabled, $(context) refers to the HTMLDocument. With same page preview enabled, $(context) refers to the element containing the preview, not the whole page.
Needs work

The change is currently missing an automated test that fails when run with the original code, and succeeds when the bug has been fixed.
Not sure how but is there a test case that can be written to show this is a problem.
