Infinite Scroll: Pinterest embeds fail to load after initial page load

[sixhours]

Steps to reproduce the issue

1) Activate any theme with Infinite Scroll support - we've tested Dara, Karuna, and Twenty Fifteen. 2) Add several posts (at least 8 to trigger infinite scrolling with multiple pages) with Pinterest embeds in each. 3) View the blog and scroll through the posts. Any posts loaded after page 1 will show an empty space where the Pinterest embed would be.

What I expected

Pinterest embeds should display in all posts.

What happened instead

Pinterest embeds aren't shown beyond the first page of posts. Likely similar to #4033 #7445 and others.
