When a contentEdtiable region has varying font sizes, the background only applies to the smallest of the two fonts. The larger characters do not have full backgrounds.

Reproducible: Always

Steps to Reproduce:
1. Make a page with a contentEditable region
2. Enter markup with a constant background color but with varying font sizes (e.g. 12pt and 48pt)
Actual Results:  
The background only covers up to the smaller of the fonts

Expected Results:  
The background covers the text according to the text size.

This is not an issue with contentEditable.
If you remove contentEditable from your example, the red background still covers only the smaller font size. This is consistent with latest versions of Safari, Chrome, Opera, and also IE8 if you include a doctype.

This is still a problem with 3.6.13 and 4.0b9.
Opera and Webkit also show the problem rendering.
IE behaves the way I would expect the rendering to work.
