OEmbed endpoint ignores parameters (like color, auto_play...)

OEmbed endpoint ignores additional parameters causing default player behaviour in Iframe

Issue found of: August 26th, 2021

Endpoint(s):

• GET /oembed

Scope(s):

• Not sure, it affects js SDK integration

Steps to reproduce:

Sending additional parameters as described in the docs

curl --request GET \
  --url 'https://soundcloud.com/oembed?format=json&color=%23E8CFD3&auto_play=true&url=https://soundcloud.com/forss/flickermood'

Expected behaviour:

The Iframe src tag in the html field of the response should contain additional params: "color=#E8CFD3&auto_play=true"
https://w.soundcloud.com/player/?visual=true&url=https%3A%2F%2Fapi.soundcloud.com%2Ftracks%2F293&show_artwork=true&color=#E8CFD3&auto_play=true

Actual behaviour:

The response ignores any of the parameters described in the documentation
"https://w.soundcloud.com/player/?visual=true&url=https%3A%2F%2Fapi.soundcloud.com%2Ftracks%2F293&show_artwork=true"

Start with the GET /oembed endpoint and compare its response with the parameters documented for the OEmbed API. Reproduce the request using the curl example, then verify that the html iframe src includes color and auto_play in addition to the existing parameters.
