TYPO3 Core

This bug I have found on each Typo 4.0+ versions. It makes problem only with Internet Explorer (6.0+7.0), Firefox is OK.

1. I select some part of text and click on the icon "textcolor", JS window comes with predefined colors, I choose a color (screen nr. 01).

2. The color seems to be applied (screen nr. 02)

3. But when I switch to HTML source code (in RTE) there si no code for text-color formating like ... span style="color: rgb(156, 0, 78);" ... (screen nr. 03). When I switch back to nonHTML mode of RTE the color of text is lost. It does not help, when I do not switch to HTML code and after aplying of color I immediately save the content element.

4. When I try to do the same in Firefox, everything works fine, also source code have the formatting code after aplying selected color (see screen 04)

Additonal info:
Typo3 4.1.1
rtehtmlarea 1.5.2
