First of all, I am really frustrated and annoyed in the meanwhile that basic functionality of the components I've just started using is buggy as hell and that the only feedback I get is "we'll look into it" with no ETA when the problems are going to be fixed. I have to spend a lot of my time finding work-arounds for bugs or quirks that should've been found during a QA process on your side especially since we don't get the components for free and a lot of MDB's functionality is built around the free Bootstrap library.

Expected behavior

The setValue method of the Select component does what the documentation says and sets the value of the Select to the given string or array no matter which option was previously selected.

Actual behavior

setValue does not reset the selected attribute of the option elements. In the code snippet linked below, click on the button that calls setValue(['7', '8']). Instead of having the value set to 7 and 8, you end up with 1, 4, 7, 8.
