1061866 - [contenteditable] data tags are stripped when pasting into a contenteditable element

Status: UNCONFIRMED

(Core :: DOM: Editor, defect, P5)

Description

[Ben Demboski]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.94 Safari/537.36

Steps to reproduce:

1. Go to http://jsfiddle.net/df6p6w2L/5/
2. Highlight the contents of the contenteditable div and press ctrl-x/cmd-x to cut it
3. Press ctrl-v/cmd-v to paste back into the contenteditable div

This also repros when copying, or when only cutting/copying a sub-range of the content (as long as it includes the <data> element).


Actual results:

As you can see in the "Editor contents" section, the newly-pasted content will be "Some text here" -- the <data> element has been removed and replaced with its contained content ("text").


Expected results:

The newly-pasted content should be "Some <data value="somevalue">text</data> here" i.e. should be identical to what was in the contenteditable div when it was cut.

Chromium does not exhibit this behavior -- it preserves the <data> element. Also, it appears to be an issue on the paste end, not on the cut end, because cutting content out of Chromium and pasting into Firefox exhibits this bug, and cutting content from Firefox and pasting into Chromium does not exhibit this bug.

Bulk-downgrade of unassigned, >=3 years untouched DOM/Storage bug's priority.
