RFR: 8185831: Psuedo selectors do not appear to work in Node.lookupAll()

[Sai Pradeep Dandem]

**Issue:**
Using pseudo classes in programmatic query using Node.lookupAll() or Node.lookup() gives unexpected results.

**Cause:**
There is no check for checking the psuedo states matching in the applies() method of SimpleSelector.java.

**Fix:**
Included the check for the states for matching.
