## What is the current behavior?

avoid applying status bar style changes to the card modal.

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by

- Ionic Framework's detection for applying status bar styles will be
based on the APIs available in Capacitor 3+.
- Ionic Framework will no longer support the legacy Capacitor 2
configurations.
