Pinterest oEmbed fails with .co.uk TLD

[gemmaevans]

Inserting a Pinterest URL containing a .co.uk TLD does not embed a board, profile or individual pins.

Steps to reproduce

1. Go to Pinterest
2. Copy the URL of a board containing a Pinterest .co.uk TLD. For example:

https://www.pinterest.co.uk/stayandroam/blue-and-white/

3. Go to Posts > Add New
4. Click on the Visual editor tab
5. Paste in the URL from step 2 (.co.uk TLD)
6. Publish the post
7. View the post on the front end

Expected

I expected to see the Pinterest board embedded in my post.

Actual

The Pinterest board was displayed as a URL rather than embedded into the post. However, I was able to successfully embed the Pinterest board by changing the Pinterest TLD from .co.uk to .com:

https://www.pinterest.com/stayandroam/blue-and-white/

Once the URL had been updated and the post was saved, the Pinterest board was embedded.

Tested
WordPress version 4.8.2

Is Pinterest in Core as an oEmbed provider? I tried looking for it and found no reference to it in v4.8.2 and I looked in the /wp-includes/class-oembed.php file to double check. This may sound silly, but just in case I've missed something/gone mad, do you have a plugin installed for this? @gemmaevans

I've double checked and I don't have any Pinterest plugins installed on my site.

Hi @gemmaevans,
this may not only be a a plugin related to Pinterest.

If you deactivate all your plugins, WordPress shouldn't be rendering pinterest.com at all.

Didn't mean to close, sorry.

Replying to mzwillus:
This appears to be a Jetpack issue so I've created a separate bug report on their repository: ​https://github.com/Automattic/jetpack/issues/7968.

I'll go ahead and close this.

Thanks for taking a look :)
