Inconsistent term.onData Event Behavior Between iOS and Android in React Native WebView Terminal

Expected Behavior:
The term.onData event should trigger immediately on every key press in both iOS and Android platforms.

Actual Behavior:

iOS: The term.onData event fires immediately on every key press, as expected.
Android: The term.onData event only fires when the Enter key is pressed twice.

Additional Information:

I've tried different configurations and approaches, but the issue persists only on Android.
It seems like the data from the keyboard input is being buffered and only sent after pressing Enter twice.

Could anyone provide insights or solutions to ensure consistent behavior of the term.onData event on both iOS and Android platforms?

This is most likely caused by a software keyboard intercepting keypresses until it sees a "commit char". We have several issues regarding android key input with different keyboard apps, none brought up any good solution yet.
