In JavaFX WebView it's impossible to style the appearance of the item-list in <select>-dropdown-fields.
What I'm trying to do, is change the font-size of the drop-down list, so that the look-and-feel of the webside I'm integrating with JavaFX is consistent.

There is a stackoverflow ticket with further information:
