QML/JS Auto-formatting removes JavaScript spread operator (ellipsis).

When a qml- or js-file containing JavaScript code using the spread operator (ellipsis) is auto-formatted, the spread operator is simply removed from the code.

Example:
Before formatting:

console.log(Math.max(...[1, 2, 3, 4]))

After formatting:

console.log(Math.max([1, 2, 3, 4]))
