TYPO3 Core

When copying some elements (I don't know the exact conditions yet) that have a custom line-height set by CSS rules, htmlarea inserts unneeded and unwanted inline style attributes to elements.

1. Add
   

   ul { line-height: 150%; color: red; }

   
   to the RTE.default.contentCSS file
2. Insert a new text element
3. Type a, ENTER, b
4. Make sure the text is colored red, i.e. the contentCSS was correctly loaded
5. Select all text with Ctrl+A
6. Click the "Bulleted List" button in the toolbar
7. Copy the text with Ctrl+C
8. Go to the end of the text with END
9. Type ENTER two times to generate a new paragraph
10. Paste the text with Ctrl+V
11. Look at the generated HTML source. It will be:
    

    <ul><li>a</li><li>b</li></ul><ul style="line-height: 27px; "><li>a</li><li>b</li></ul>

    
    The style="" is unnecessary.

It only happens in Webkit browsers (tested in epiphany). Happens every time.
