Therefore it is not only the content of this element that is editable, but some properties of the element itself (both position and dimensions). This behavior is specific to mozilla's implementation of contenteditable. It is not featured in the original IE's implentation, opera nor webkit implementation. It is not described in the WHATWg draft either: http://www.whatwg.org/specs/web-apps/current-work/#contenteditable This behavior should be removed. Reproducible: Always Steps to Reproduce: 1. open an html document containing an element with position: absolute and contenteditable="true" 2. click on this element Actual Results: you can drag and resize the element in the page Expected Results: You should only be able to edit the _content_ of this element. You should be able to drag and resize absolute positioned element only _inside_ this element. You shouldn't be able to drag and resize the element itself

Summary: native midas's draggable/resizable features applied to elements with position: absolute and contenteditable= true → elements with contenteditable=true and position:absolute can be moved around the page
This particular feature probably has its roots in Composer's layer implementation. Now that contenteditable has become a part of proposed specification, Mozilla probably should look to make this behaviour Mozilla-specific and disabled by default. Currently, this can be worked around by setting the absolute-positioned element's contenteditable to false, putting the contents of the element into a seperate container element and setting the container's contenteditable to true. It should have no side effect on other browsers.

Created attachment 555122 [details] [diff] [review] patch proposal Not ready for review, I still have to write the tests. Ehsan: given the number of such bugs, should I add an optional boolean argument to these two functions (false by default) that would allow to check that the node is a strict descendant of the active editing host?
oops. By these two functions I meant: nsHTMLEditor::IsModifiableNode(nsIDOMNode *aNode) nsHTMLEditor::IsNodeInActiveEditor(nsIDOMNode* aNode)

How about adding another helper function called IsEditingHost or something?

(In reply to Ehsan Akhgari [:ehsan] from comment #14) > How about adding another helper function called IsEditingHost or something? That could be an option as well but I see two main drawbacks: • the code returning the active editing host would be called twice (I don’t know if that would be expensive wrt the perfs); • an attribute of a "contenteditable" element should not be modifiable, so we need a bit more than just `IsEditingHost'. However, bug 677752 has been landed short after I’ve proposed to add an optional boolean param to IsModifiableNode / IsNodeInActiveEditor, and I think most cases where we need to check if the current node is a strict descendant of the editing host should be covered now. At this current point, I think modifying IsModifiableNode / IsNodeInActiveEditor would be mostly a matter of factorizing a few lines of code.

It turns out that the test fails on Android, so I had to mark it as such: http://hg.mozilla.org/integration/mozilla-inbound/rev/b1fbce31b7f2

This is happening in FF 29. Is it a regression?
