If you go to a web page with many images, JavaFx WebView uses way too much heap to load the web page.

For example, this particular web page has 340 images:

https://github.com/d3/d3/wiki/Gallery

JavaFx WebView takes around 2GB of heap in order to render the page.
Firefox takes around 500 MB. Please reduce the heap usage as less as that of FireFox


When using JavaSE8u112 to run attached JavaFX program,
we get heap overflow with 1 GB heap. The backtrace of the overflow is shown below.
