In TinyMCE frames (Wysiwyg API module), Admin theme's style.css rules don't apply because there is no #content wrapper there.
So only reset.css rules apply, which in effect removes all formatting inside the editor's frame.
Workaround: in admin/settings/wysiwyg/profile/#/edit, section "CSS", set "Editor CSS" to something other than "Use theme CSS".

emptyvoid commentedSorry to hear you are having problems.
I am using FCKeditor and it works just fine, perhaps you should try another editor?
Comment #2
siteograf commentedFCKeditor ignores user-defined styles also, when admin module is active.
Comment #3
siteograf commentedProblem has been solved with FCKeditor after defining full path to custom css file without placeholders.
Doesn't work: %h%teditor.css
Work well: /themes/theme_name/editor.css
