All Telerik .NET tools and Kendo UI JavaScript components in one package. Now enhanced with:
<
input
id
=
"quantity"
class
"qty"
value
"1"
disabled
"disabled"
/>
I could not reproduce the depicted issue. Check this jsFiddle demo. Let me know if I am missing something.
This seams to be related with the Firefox itself. Check this thread for more information.
