1147485 - document.execCommand('insertOrderedList') in foreignObject generates invalid document structure

Status: UNCONFIRMED

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

Description

[Dan Burzo]

Attachment: document_execcommand_foreignobject.html

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:36.0) Gecko/20100101 Firefox/36.0
Build ID: 20150320202338

Steps to reproduce:

I've created a test file for this.

1. Open the file in Firefox
2. Focus on the part that says " With focus here, it should not work. "
3. Press Ctrl+A to trigger a document.execCommand('insertOrderedList').


Actual results:

Visual shift. Inspecting the page with Developer Tools reveals invalid DOM (multiple SVG / foreignObject elements).


Expected results:

The text "With focus here, it should not work." should become a one-item <OL>.
(It happens correctly if the contenteditable div is not inside svg > foreignObject)

Thanks for the testcase! I see this in the Nightly build on OS X too.

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

If you have reason to believe this is wrong, please write a comment and ni :jstutte.
