MediaElement playbackRate not working

Hi everyone.
We have seen an issue changing the playback rate in a video element.
We have a test app for testing different video players. In this case, we using shaka player
and we are changing playbackRate property but the speed is not changed.
In the case we launch the same app running in a web server through the navigator app, playbackRate change is working correctly.

Is there any known issue about this? Is there any solution or workaround?

Thanks in advance,

We cannot check 3rd party player issues. You can use the playbackRate with the native player, but the sound is not supported in this case. Therefore, it is not appropriate to use it to control the playback speed. Thank you.
