bug: CapacitorHttp - No support for Server-Sent Events (EventSource API)

[torte]

Bug Report

Capacitor Version

@capacitor/cli: 4.7.0 @capacitor/core: 4.7.0 @capacitor/ios: 4.7.0 @capacitor/android: 4.7.0

Platform(s)

iOS and Android regardless of version

Current Behavior

When using the web's EventSource API for use with Server-Sent Events, the CapacitorHttp plugin won't be used and instead it falls back to the web's native implementation. This is caused CORS issues when intending to use device's native HTTP handling (hence the usage of CapacitorHttp).

Expected Behavior

As with fetch and XMLHttpRequest, EventSource should also be patched and work through device native events.

Additional Context

Likely related to other issues similar to this since the Content-Type is text/event-stream for Server-Sent events: https://github.com/ionic-team/capacitor/issues/6299 & https://github.com/ionic-team/capacitor/pull/6206 ?
