Mac Mail app in Sequoia won't show single page PDF previews inline when composing

After upgrading to Sequoia, the mail app will no longer show single page PDF previews inline when composing a message, and will just show the icon. Right clicking on the icon has the "view in place" option grayed out. Having these PDF attachment previews is helpful to our workflow, so hoping to find an option to get this back. Once the message has been sent, the attachment preview will show inline, just not when composing the original massage.

Other image file types appear to show the previews just fine, and trying to use terminal commands to reset the behavior so far has been unsuccessful.
