Describe the bug

When an application targets Android 15 (API 35), the app renders in edge-to-edge mode, drawing behind system bars. This applies to libraries that display UI like Braintree.

Upon targeting API 35, many Braintree and Cardinal SDK (3DS) are not supporting edge-to-edge which causes certain content to be hidden by system UI.

The Google Pay option is not clickable

Top toolbar content is obscured by the status bar

Top toolbar content is obscured by the status bar

To reproduce

1. Target Android 15 (API 35)
2. Display Braintree Drop-in
3. See content is obscured by system UI

This can be reproduce by making the demo target Android 15

Expected behavior

The content is not obscured by system UI.
