Current Behavior

Video playback is paused (and not resumed) when reading cookie with CapacitorCookies enabled.

Expected Behavior

Video playback should be uninterrupted by cookie retrieval.

Additional Information

The use of prompt(JSON.stringify({type: 'CapacitorCookies.get'})) causes video playback to be paused:

capacitor/core/native-bridge.ts

Lines 418 to 426 in 1834b97

	if (platform === 'ios') {
	// Use prompt to synchronously get cookies.
	// https://stackoverflow.com/questions/29249132/wkwebview-complex-communication-between-javascript-native-code/49474323#49474323
	const payload = {
	type: 'CapacitorCookies.get',
	};
	const res = prompt(JSON.stringify(payload));

This is particularly problematic with a library like mux where the library is repeatedly setting cookie while the video is playing.

This doesn't happen on iOS 16 devices (My iPhone 8).
