Current behavior

When defining a custom cell template by defining a new Vue component few Vue warnings appear in the console. Here are the errors:

• [Vue warn]: Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. Instead, use a data or computed property based on the prop's value. Prop being mutated: "dataItem"
• [Vue warn]: $listeners is read-only.

Expected behavior

There should be any errors in the console when defining a cell template using a Vue component.

Minimal reproduction of the problem with instructions

1. Open this Dojo example
2. Sort the Grid by any column
3. See the browser's console
