I think there is a tag missing from the scrubber-allow:
Affected RT version
Our RT is 3.4.4pre
By using PreferRichText sometimes the text appears without formatting.
The problem occures when the richtext is not a normal html doc, but a
classic text (I mean: linebreak is chr(13) not
and spaces are
spaces). In a html document a part like this has to be enclosed by(‘pre’ means preformatted text). The bug: after these tags
have been eliminated by the scrubber, the text will have displayed
without formatting (no line breaks, no tabs, no spaces).
Insert PRE into the scrubber’s allow string. Original file:
RT3PATH/share/html/Elements/ScrubHTML, line 64.
