theme change transition is removed due to transition stacking in webkit browsers. Need to find a way around this

The previous css implementation is commented in style/index.css line number: 39 - 42. The implementation that created the bug was:

* {
    transition: color 0.3s ease-in-out, box-shadow 0.3s ease-out, background-color 0.7s ease-out, background-image 0.3s ease-out;
    -webkit-transition: color 0.3s ease-in-out, box-shadow 0.3s ease-out, background-color 0.7s ease-out, background-image 0.3s ease-out;
}
