Custom Tabs Action Button icon showing in black


I’m currently exploring on a demo app launching Custom Tabs, for that end I’m just launching url, and trying to add an Action button with an Bitmap icon in the toolbar. So the issue I’m facing is that the icon is showing in black color and overriding the icon design itself. This issue is not happening with Chrome, Firefox, MS Edge.

Is this a know issue/feature or there is a way to make the toolbar to show the original Bitmap provided to show the Action button.


Can you share some screenshots of your experience?
