Change Chevron background in Edit Form

[MariaL]

This is an option that is actually available in a normal use of PowerApps but you can't do it when you are editing a Sharepoint form.

Background color and  arrow color can ben changed, but there's any available options to set the background color/arrow color in hover cases.

So the result is quite ugly and completly breaks the customised design.

Please, put also these two options in forms editability.
