Mask rules can be violated with left arrow

[Terry]

http://dojo.telerik.com/etIwa/2


<input id="maskedtextbox" />

<script>
var m = "0ba";
// this should limit the first character to 0-9, the second to 0-5, and the third to 0-2
// but enter the following:
// 9
// left arrow
// 2
// left arrow
// 3
// left arrow
// 8
// left arrow
// 9
// leaves us with "983" - only the first character is "valid"
// basically, after you left arrow it will "push" the existing characters to the right (sometimes, not always) when the next character is entered

$("#maskedtextbox").kendoMaskedTextBox({
mask: m,
    rules: {
      // "0" allows 0-9
      "b": function (char) {
        return (char === "0" || char === "1" || char === "2" || 
                    char === "3" || char === "4" || char === "5");
      },
      "a": function (char) {
        return (char === "0" || char === "1" || char === "2");
      }
    }
});
</script>

Hello Terry,

Thank you for drawing our attention to this issue. Currently, widget just pushes the rest of the input to the right, instead of validating the newly created value. I logged this erroneous behavior for further investigation and fix.

As a gratitude for your involvement I updated your Telerik points.
