The new changes from @justinmc (#27205 and then #29250) are great but still leave me with a problem. When I set my textfield to expanded, the text is then centered vertically, whereas I want it to be at the top. I can't figure out a way to do this.

I would expect the behaviour of expands to be the same as setting maxlines; that is, the text would stay at the top.

If the default cannot be changed (and now would be the time since it was only introduced recently) then an option to align the text vertically when expanded = true would be great.
