TYPO3 Core

Adding a textfield to typo3 and marking and setting some text as centered changes the following example:
<p>oh what a nice peace of text</p>
into:
<p class="align-center">oh what a nice peace of text</p>

That's pretty good, but when you try to change it again (p.e.: right-align) then the result is:
<p class="align-center align-right ">oh what a nice peace of text</p>

And the element is displayed with [text-align:center;]

TemplaVoila 1.4.2
Firefox 3.6
RTE 1.8.8

I updated the t3-system from version 4.2.12 to 4.3.2 but the problem remains the same. I also switched to tinyrte-extension but this doesn't help neither.

I checkek with firebug, to be sure to NOT override the alignment with my own css-stylesheet.

I checked it with another t3-installation and there is the same problem. Combining an "align-center" with "name-of-person" is also not possible.
