Content assist doesn't work for "styleClass" and "class" attributes. It should display available style classes.

Steps to reproduce:
1. EXECUTE: create style class in jsp (or any) file
<style type="text/css">
.myStyle

</style>
2. EXECUTE: create any component where user can use "styleClass" or "class" attributes (<h:outputText> e.g.)
3. EXECUTE: create "styleClass" or "class" attributes and try to use CA for choosing "myStyle"
=> CA doesn't work
