Querystring too long in EPiServer Composer

Stumbled upon an issue with EPiServer Composer 4 and that the query string was too long. Not entirely sure how great this fix is out of a security stand point, but if anyone else knows a better solution please let me know.

The error
HTTP Error 404.15 - Not Found
The request filtering module is configured to deny a request where the query string is too long.

The solution

    <system.webServer>
        <security>
            <requestFiltering>
                <requestLimits maxQueryString="2097151" />
            </requestFiltering>
        </security>
</system.webServer>
