Wordpress seems to have a problem with its pages if the page has embed query param and thus we mustn't forward that.

We forward all the existing query params which is required but we shouldn't forward the embed query param (which stores the embed namespace), which is used only in case of embed.

We should also add some kind of test(preferrably unit test) to verify that embed query param isn't forwarded and all other existing params and some special params that we are supposed to forward are being forwarded
