Request for Help: Flutter Web App Lagging on iOS When Routed via Istio in Kubernetes

Hey Flutter & Kubernetes community,

We're experiencing a strange issue with a Flutter Web app deployed in Kubernetes behind Istio.
Everything works smoothly in most environments, but when accessed via iOS browsers (Safari, Chrome, Firefox) through Istio, scrolling lags significantly and throws the following runtime error:

TypeError: null is not an object (evaluating 'r.b')
