different behavior on different browsers: background or text color

[ken]

in a CKEditor.

1. Type some words ,click background color button to choose a background. then continue to type some words.
2. On IE and FF, these newly added words will have the background color. but in Chrome, the background color will not be applied to these newly added words.

another similar case is:

1. Type some words ,select all these words, click background color button to choose a background to apply, then all the words will have this background color. click ENTER to a next line then type words.

2.On IE and FF, the new line will have the same background color as previous. but chrome not.

both background and foreground(text) color have such issue. i checked it in the nightly build (6280),it still exists
