Browser compatibility: buttons not visible

[GoogleCodeExporter]

Buttons are not displayed in Firefox.

What steps will reproduce the problem?

View openhab.app?sitemap=demo page group demo or Widget overview in Firefox an 
a system were Chrome is not installed and was never installed before.

What is the expected output? What do you see instead?

E.g. the following buttons on the demo sitemap are NOT Visible:
- page group demo, line All lights, the button "all off" in the first line
- page Widget overview, second line: the button switch "on"
- page Widget overview, line Scene, the three buttons "TV", "Dinner" and 
"Reading"

The buttons are obviously there, because the mouse pointer changes over the 
button and when pressing the mouse button the action is also initiated as the 
openhab console shows. The buttons are just not visible.

What version of the product are you using? On what operating system?

Openhab1.1
I tried on
1. Win XP SP2 with Firefox 14.0.1
2. Win XP SP3 with Firefox 18.0
3. Win7 with Firefox 18.0
4. Win7 with Firefox 18.0.1
Same problem on all of them.

Please provide any additional information below.

After installing Chrome on system 1 (Win XP SP2 with Firefox 14.0.1) the 
buttons show up as expected also in Firefox. But this is not a solution.

This is a known limitation of the used web UI framework. There is a note in the 
wiki that it only works correctly with WebKit-based browsers.
