DOMException: Failed to read the 'selectionDirection' property from 'HTMLInputElement': The input element's type ('number') does not support selection.

Chrome currently throws this error:
DOMException: Failed to read the 'selectionDirection' property from 'HTMLInputElement': The input element's type ('number') does not support selection.

I've worked around this by adjusting the script to the following, temporarily making the field type not 'number':

    $(this).keypress(function (event) {
        if (!event.charCode) return true;
        var elType = this.type;
        this.type = 'text';
        var part1 = this.value.substring(0,this.selectionStart);
        var part2 = this.value.substring(this.selectionEnd,this.value.length);
        this.type = elType;
        if (!mask.test(part1 + String.fromCharCode(event.charCode) + part2))
            return false;
    });
