Description

Pinterest URLs that don't come from the .com domain won't be embedded.
Pinterest uses a different domain for different countries and people in those countries might find it difficult to use this block.

Step-by-step reproduction instructions

For example, these URLs won't get embedded:
https://www.pinterest.es/pin/320670435980314659/
https://www.pinterest.it/pin/308004062030905959/

But changing the .es and .it for .comwill make it work:
https://www.pinterest.com/pin/320670435980314659/
https://www.pinterest.com/pin/308004062030905959/

Expected behaviour

Any URL coming from the existing interest domains in each country should work.
Having a list of them should be enough to deal with this.

Actual behaviour

URLs won't embed if not coming from the .com domain.
