The iframe's overflow is causing issues in responsive design.

The responsive behavior of the iframe is not handling overflowed content as expected.

Iframe has been given an inline width causing it to overflow content.

Use the following CSS for mobile devices:

@media only screen and (max-width: 767px) {
  	.bbp-topic-content iframe.wp-embedded-content {
	    width: 100%;
	}
}
