I tried to use embed tag and it works !!

Please convert iframe tag to embed tag in the main webpage.

Strange thing is that the browser added "</embed>" at the end of the embed tag.

Embed doesn't require closing tag but, here, it was automatically added.

Please add the same thing (</embed>) next time you try embed tag.

Maybe, that's the reason embed tag didn't work ??

Another thing may be that embed and iframe tags doesn't want to co-exist in a same webpage ??

I am not sure but we will have to find out as we go along.

Thank you!!
