[BadgeDrawable] Color selector not being respected for badge background

[pedronveloso]

Description: Adding a color selector to the badgeStyle -> backgroundColor doesn't see to work as expected. Color doesn't change when Tab is selected.

Expected behavior: Badge color would respect color selector

Source code:

I've tried every single property I could find, and it didn't make a difference. Here's a sample example:

<style name="StudioBadge" parent="Widget.MaterialComponents.Badge">
    <item name="backgroundColor">@color/badge_bg</item>
    <item name="badgeTextColor">@color/badge_text</item>
</style>

And badge_bg looks like this:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_selected="true" android:color="@color/color_one"/>
    <item android:color="@color/color_two"/>
</selector>

In this example, only color_two gets applied to the badge, even though following the same process the tab text changes accordingly.

We don't support color state list for badge's background color for now.

Changed this to a feature request.
