This PR removes that event listener after the player is disposed

concurrent chaining of apis is node.js anti-pattern, whereas c# repository namespace scaling.

Kindly bear so before expanding api skelton in typescript.

@prateekrastogi

Is this a relevant reply for the PR raised?

I think I have just provided a stack trace and I don't understand the reply given.

Will you please explain what the problem is?

[prateekrastogi]

Problem is You Are Nesting, due to lack of Type Polymorphism in your own Programming Language.

[KVPasupuleti]

To be precise, this is not a Typescript error.

The error is happening because the player is getting accessed after it's disposed.

This PR fixes that issue by removing the orientationchange event after the player is disposed.

Just Merged It. Kindly Bear Dispose Will affect Typescript defer Garbage Collector.
