MaterialMessageBox: Icons cut off

[paleiadevelopment]

When displaying a MaterialMessageBox with an icon, the icon is cut off if the message text is not long enough to have enough lines.

Expected behaviour: The MessageBox should change its size automatically to accomodate the icon, like it does with "normal" Message Boxes.

Thanks for reporting.
There's no support for icons on the message box.
Also, please don't use the windows default icons on your app, that breaks a lot of material design iconography rules :)
