I haven't tested this but I suspect that setting the else rule
(`rule.setElseFilter(true);`) is the problem as it means the rule will only
be executed if the filters of the other rules return false, as you only
have one rule I'm not at all sure what the renderer would do (stepping
through with the debugger would be the "easy" way to answer that) for the
time being I'd just remove that line and see if it fixes it.
