Describe the bug

compared to Entry, MultiLineEntry and SelectType, Select has the wrong height, padding and border.

it doesn't have a border all around, but instead just a border on the bottom. the padding inside Select seems to be less. the padding outside is wrong (?).

this is especially visible in a Form widget. there, the label doesn't align properly with the Select.

How to reproduce

open fyne demo and go to input widgets
