[ToggleSplitButton] Inaccurate color palette for Checked & Disabled state

[ToukZ]

Describe the bug

ToggleSplitButton accepts both the IsEnabled and IsChecked properties, but when both of those properties meet, the coloring of the button fails to represent them both (see Screenshot below, happens on both Light Mode and Dark Mode).

What it feels currently is that the component is simply Enabled and Checked, since the bright blue coloring portrays as such.

Steps to reproduce the bug

1. Go To 'ToggleSplitButton' Page;
2. Click the button to 'Check' it;
3. Set the 'IsEnabled' property of the button on code to 'False';
4. See Error.

Expected behavior

Button should properly convey by their color that it is Checked and Disabled to the user.
