icon button is not a circle

[Orasund]

The icon button is not a circle. As can be seen on the website.

~This will be fixed in version 3.0.0.~

~It would take some effort to fix in version 2.3.1.~

~Please respond to this issue if you need this fix asap.~

This bug relates to https://github.com/mdgriffith/elm-ui/issues/270.

I will need to come back to this issue once it's fixed.

An easy fix is to use

Material.iconButton |> Customize.elementButton [Element.width Element.shrink]
