Wrong proposals appear in CA Window for CSS styles inside <style></style> tag when:

1. There is at least one whitespace character is placed between opening and closing "style" tags
and
2. The CA is invoked when the cursor is pointed right before the closing tag (i.e. "<style type="text/css"> |</style>", where "|"-char indicates the cursor position.

In such cases WTP suggests proposals for a new tags insertion, but not the CSS proposals.

Probably it's WTP's issue, because:

1. WTP decides which kind of proposals are to be calculated at some cursor position.
2. We don't add any computers for CSS proposals since WTP 3.2

JUnit test org.jboss.tools.jst.jsp.test.ca.Jbide1791Test fails because of this issue.
