When deleting multiple lines of text, subsequent folded regions might get expanded.

E.g.

public class Foo {
    static void m1() {
        // delete me
        // delete me
        // delete me
        // delete me
        // delete me
        // delete me
    }
    static void m2() {
        // fold me
    }
    static void m3() {
        // fold me
    }
    static void m4() {
        // fold me
    }
}

Fold methods m2-m4 and then delete the comments in m1. Methods m2-m4 get expanded.

The culprit seems to be ProjectionViewer.handleVisibleDocumentChanged() where in case of a delete with multiple lines, the complete range of the (now deleted) text is expanded.
