That's quite contrary to my experience. Even for old emacs like emacs22
font-lock is kept on marked text with transient-mark-mode enabled.
As to other tools like Eclipse, Netbeans,Xcode selected text does not
lose syntax highlight either. 

Especially for Eclipse I remembered that when I used it about a decade
ago copying selected code from Eclipse to other WYSIWYG applications
like MS PowerPoint the syntax highlight is also copied ie, rich formatted.

I must say here that my experience with color theme is way much better
and much less flaws than before it's integerated thanks to the work of
all the developers especially cyd.

I hope the feature be kept without introducing too much maitainabitly
burden, with code both easier for user to understand and theme writers
to customize.

I do. I find myself get an uneasy feeling when font-lock is lost on
marked text.
