Actually, it's a bug in The SEO Framework.
While the specific issue stems from an incompatibility with what The SEO Framework does, @sybrew's analysis in https://github.com/sybrew/the-seo-framework/issues/436 is not completely wrong: Several filter hooks used by wp-Typography since "forever" don't expect added HTML markup (or at least it's not clear that users of the relevant functions should expect to handle HTML in the returned values).
Processing the title parts should not result in HTML tags (
<span class="caps">
etc.) being added, as ´Reported in the WordPress forums.
