Test multiple transitions on same element

[IanLunn]

It is most likely that multiple transitions on the same element won't work correctly when transitions are reversed.

Example code:

.some-element {
    color: red;
    left: 0;
    transition: color 1s, left 2s;
}

.some-element.animate-in {
    color: blue;
    left: 50%;
}
