Form elements (input, text-area, etc) start with undefined instead of empty string

[enfJoao]

dnn-input id="wName" minlength="10" required=""></dnn-input>

console.log("Name: " + document.getElementById("wName").value);

In this example, the console will log undefined until the input is changed. Then it will log "".

Inputs should start with "" to prevent all associated issues in validation and values handling.
