Opening with the _self target not working

# Bug Report

When using _self - nothing appears with no errors reported. If I change it to _blank it shows up but leaving a large gap at the top and the whole thing can be swiped down to close it. I'd like to be able to just open it fullscreen without any ability to close it by pulling down.

### What is expected to happen?

_self should let the browser replace the current ionic webview if I'm not mistaken.

### What does actually happen?

Nothing at all.

## Checklist

- [x ] I searched for existing GitHub issues
- [ x] I updated all Cordova tooling to most recent version
- [x ] I included all the necessary information above

The report names no source file, test, command, or platform-specific reproduction. Start by reproducing the _self and _blank target behavior in the stated Ionic/Angular and Capacitor setup, then trace the plugin's target handling; done means _self replaces the current webview fullscreen without an unintended pull-to-close gesture.
