Button/ImageButton's Border has a default value on Windows

[AllenMiaoFil]

Description

When I tried to add a Button and an ImageButton into page, there is a default button border around Button, but I've never set button border. I must set it to 0 explicitly so that the Border is removed. and it also effect ImageButton.
In below screenshot you can see the Button2 has a default BorderThickness(Im not quite sure it is the root issue, but when I tried to modify it's value, the border width is modified).

This below screenshot you can see the Button3, I set BorderWidth="0", then it works well(But the default BorderThickness value is 1, I think maybe BorderWidth style override the default value).

It also has seem issue on ImageButton, but I can't reproduce in this simple project, can do you a research on ImageButton?
I can show my pervious screenshot.

Steps to Reproduce

1.Create a MAUI project
2. Add a Image button and set button BackgroundColor to Transparent.
3. Add a Button set button BackgroundColor to Transparent.
4. Run program.

This issue only on Windows, I checked on MacOS, it works well. I also attached a simple project.
ImageButton.zip

The default value of StrokeThickness is -1 and with that value, Windows is using the default value. We can solve this, and the attached example would be:

However, buttons without a background color would look different:

@Redth What do you think?

@mattleibow you did a fair amount of work in this area, to me this seems like we don't want to make this change and it's expected you must override the defaults explicitly.

Testing with the latest 7.0 version, the behavior is the correct one:

By default, set the default BorderWidth, setting 0 remove the Border and setting a custom value modify the border thickness.
