Blog Posts Page: Older Posts with Twitter Embeds not Rendering

### Quick summary

On the blog posts page, on first load, Twitter posts will show in an attractive iframe-looking container. However, if there are older posts on a page, these will not load the embed container, and only show a text version of the Twitter content inside.

Other embeds I looked at (YouTube, Imgur) seemed to work, so I am not sure if this is just Twitter embeds or not.

### Steps to reproduce

1. Make some number of post with twitter embeds greater than the number of displayed posts, so that an older posts button appears.
2. Look at blog posts page, and load Older Posts

### What you expected to happen

The display of Twitter embeds would remain consistent for older posts as they seem with the older ones.

### What actually happened

The older posts appear to be missing some styling.

### Context

#29399820-hc , #4437154-zen

We temporarily postponed the problem by increasing the number of displayed posts.

Incidentally, I had tried Infinite Scroll, but saw the same issue there.

Tested in Baskerville 2, but seems to be the case in other themes too. Could not find a theme where this works as expected.

Reproduce the blog posts page with Twitter embeds on the initial posts and after selecting Older Posts, using the linked video as a visual reference. Compare the embed behavior with YouTube or Imgur and verify that Twitter content renders consistently after older posts load; the issue names no source files or tests to begin from.
