Editor can't handle absolute URL in background-image style

[Marcin]

I have this bug in Telerik ASP MVC extensions but apparently Kendo UI inherited it from MVC extensions
Steps to reproduce:

1) go to http://demos.kendoui.com/web/editor/api.html
2) set value 
<div style='background-image:url(http://demos.kendoui.com/content/shared/styles/sprite.misc.png)' >test</div>
3) click get value button

Expected value is
<div style='background-image:url(http://demos.kendoui.com/content/shared/styles/sprite.misc.png)'>test</div>
but instead we get 
<div style="background-image:url(http;">test</div>
