<boxed-text> rendering as plain text, <caption> rendering as <h3>, and <xref> not working

Describe the bug
Vendor has used <boxed-text> tag (which seems valid) to wrap an item that, in the manuscript, appeared in a box and was treated similar to a figure (i.e., centered, with smaller caption text underneath it reading "Box 1: ...."). However, in Janeway, a number of things happened that seem less than ideal:

• No box appears around the <boxed-text> content, nor is it otherwise distinctly formatted/indented/aligned. Instead, everything is aligned to the left margin, like the rest of the article body text. This makes it impossible to distinguish where Box 1 ends and regular text resumes (unless you inspect the elements to see the <div> tags)
• The <label> for Box 1 is displaying the same as table and figure labels. But unlike tables and figures, the <caption> text for Box 1 is improperly rendering as <h3>, making it appear to be a subsection and linked on the TOC (with a duplicate name as the section it's nested within)
• A link in the previous paragraph (<xref rid="BX1" ref-type="boxed-text">Box 1</xref>) is not directing to Box 1 as expected; it should work the same as any <xref> pointing to a figure or table.

Janeway version
1.4.2

To Reproduce
Steps to reproduce the behavior:

1. Go to https://journals.publishing.umich.edu/ptpbio/plugins/typesetting/preview_galley/article/2096/galley/959/#heading13
2. Scroll down to 'Box 1:'
3. Note the issues described above.

Expected behavior
Everything wrapped in <boxed-text> should appear within a visible box (either a solid border or a shaded background) so that the contents of that element are easily identified. <label> and <caption> should render the same as they do for either tables or figures, depending on whether you choose to display a border or a shaded background. This element should be linkable just like a table or figure.

Additional context
I'm not certain if this is a bug (i.e., <boxed-text> is expected to work in Janeway, but it isn't) or a feature request (i.e., there hasn't been any work to render <boxed-text> in a particular way in Janeway) but regardless, there appear to be some issues with the current rendering of this tag. In the meantime, as a workaround, perhaps we can just tag it as a single-celled table.

Start with the typesetting preview URL and inspect how the JATS elements , , , and are rendered. Verify the current output against the reported box, caption heading, table-of-contents, and link behaviors; done means boxed text is visually distinct, its caption matches figure or table styling, and references link to it.
