w2ui grid - password renderer error if password undefined

[ope-nz]

Hello, when inserting a new row into the grid (without a template) the password renderer is throwing an error as the value is "undefined"

What is current behavior
The error below is thrown if the value is undefined and the new row is not added.

What is desired behavior
The password renderer should be blank until the password value is set.

Steps to reproduce or sample
See console output in codepen

Proposed fix

In w2utils.js update 'password' renderer to;

'password'(value, params) {
let ret = ''
if (!value) return ret;
for (let i = 0; i < value.length; i++) {
ret += '*'
}
return ret
}
