When displaying by default, FX 8 Java console is getting cut offL contents and buttons are incomplete displayed

*** Tested Configuration:
- x86 Ubuntu 12.04
- Firefox 19
- jre 8-b84

*** Steps to reproduce:
0) Install jre 8-b84
1) Configure Firefox to use the above plug-in
2) Configure java console to 'show console'
3) Use Firefox to invoke any JavaFX applet
e.g. http://jre.us.oracle.com/java/re/javafx/8.0/promoted/latest/binaries/linux-i586/javafx-samples-8.0.0-ea/BouncingBalls.html

if you see the default content of java console is cut off (as attached screenshot), the issue is reproducible
