Bug 91783 – execCommand copies the backgroung-color of the enclosing element to the element being edited.

• Status: RESOLVED
• Resolution: FIXED
• Component: HTML Editing

[Ryosuke Niwa]

What steps will reproduce the problem?
1. Open a blank/any page.
2. Open the developer tool console.
3. Execute the following JS from the console:

var body = document.getElementsByTagName('body')[0];
body.contentEditable = true;
body.style['cssText'] = 'background-color: white;';

4. Now type some text into the page. (e.g aaa)
5. select the text typed in 4.
6. from the js console:

document.execCommand('insertUnorderedList');


What is the expected result?

body.innerHTML should give
"<ul><li>aaa</li></ul>"

What happens instead?

body.innerHTML gives
"<ul><li><span style="background-color: white; ">aaa</span></li></ul>"

Please provide any additional information below. Attach a screenshot if
possible.

It can also be reproduced with other commands e.g insertOrderedList.

The code change looks right.

> LayoutTests/editing/style/redundant-background-color.html:6
> +<script src="../../resources/testharness.js"></script>
> +<script src="../../resources/testharnessreport.js"></script>

We don't normally use testharness.js for webkit regression tests. Use dump-as-markup.js in LayoutTests/resources/ instead.
