Steps to reproduce the problem:
https://codepen.io/anon/pen/eLKdem

1. Create input of type="date"
2. Add transition rule to that input (example: transition: all 5s)
3. Change a color of input on hover
4. Input changes the color, but caret down doesn't

What is the expected behavior?
When we change the color of the date input that has a transition rule set, the color of caret down should follow that rule and transition accordingly.

What went wrong?
Instead, it won't follow the transition rule and it will only change color to ending color if you hover over it or manipulate the input. If transition rule is removed it would work. It doesn't matter how short the transition duration is, once it is set, caret doesn't change color.
