I have an issue with JavaFX WebView component.

Preconditions:

load this leaflet maps:
http://cliffcloud.github.io/Leaflet.LocationShare/

(e.g. by http://download.oracle.com/otndocs/products/javafx/2/samples/Ensemble/index.html#SAMPLES/Web/Web%20View)

overflow on map content has:
overflow: hidden

Reproduce Path:
1. click marker icon on the left
2. on input with text 'enter your message' do click and move (mouse drag) to right edge of the map
3. All of the map content is scrolled - this is the issue

Same actions on any webbrowser (firefox, chrome) not reproduce this issue.
This behavior is reproducible on webbrowser (firefox, chrome) only when overflow set on 'visible', when it's 'hidden' webbrowsers not allow to scrollcontent by mouse drag (click + move on input field).

Why javaFX browser does not behave the same way as other webbrowsers ?
