"The “default” intent has a special role: if the extendDefault property
of the StyleMap is set to true (default), symbolizers calculated for
other render intents will extend the symbolizer calcualated for the
“default” intent. So if we want selected features just to have a
different size or color, we only have to set a single property (in this
example: pointRadius)."

So, if you have (in your select style) the 'label' set to '' -- an empty
string -- I think this should solve your problem.

Vertices are features too, but I think the above solution should solve
your problem, based on your description.
