Embed failure placeholder design is broken

[youknowriad]

I believe this should look closer to the embed default placeholder with the failure message and buttons under the input?

I guess this happened with the placeholder refactorings cc @jasmussen @ItsJonQ

@youknowriad Halloo! Thank you for spotting this! I just took a looksy 🤔

The error markup HTML element isn't playing nicely with the display: flex of the form. These changes were made 1+ year ago. Not too sure why it's popping up now.

Will work on this now, and submit a fix as soon as it's ready

This may or may not be related. I'm happy to create a separate issue if it's unrelated.

I noticed a couple of irregularities when a field and a button occupy the same row. Here are a couple examples of what I'm seeing:

RSS Block

Embed Block

It seems like in both instances the input could benefit from being the same height as the button.

Hat tip to @jasmussen for pointing me to this issue.
