Adding a DTD in that file helped. I added XHTML 1.0 Transitional which
seemed to me the best choice.

I guess that CSS2 selectors don't work in quirks mode in IE7, so that's
why you have to add a DTD.

So for me now the questions are, if someone might need to run IE in the
RTE in quirks mode. If not I suggest that you add that DTD (for IE). If,
yes it'll get more complicated with IE8 which has no doctype sniffing
but a meta tag to enforce backwards compatibiliry with older IE
versions. So it should be a "ieStrict" property and not say a "ieDTD"
property.
