Previously if we crafted an HTML email we could use the @media print CSS section to force a page break before or after an element. With Thunderbird 102.9.0 the CSS for forcing a page break is being ignored in HTML emails.

If I save the message source as an HTML file and open it in Firefox the print preview shows the correct page breaks, but in Thunderbird the content all runs together.
