1. Give div width "auto" and a fixed height.
2. Add content to div such that it has width 10px
3. Set css width transition on div.
4. Set div width to 400p.

Expected results:

The draft doesn't say anything about transitions from/to auto so I'd expect no transition to occur and for the div to immediately grow in size.

Actual results:

The div immediately shrinks to a width of 0 and then grows in size to 400px. This is pretty ugly.
