In an ebook that I produced recently (PG78995), I formatted closing formulas in correspondence with the help of "ch" units instead of "em" units. If these units are too new to be used, ebookmaker doesn't give any warning related to them. In any case these CSS lines were removed from the released HTML (https://www.gutenberg.org/cache/epub/78995/pg78995-images.html), so that the closing formulas have all the same padding-right and aren't properly formatted. See for example Appendix C. The HTML "as submitted" however, still has the CSS and shows the formatting as intended (https://www.gutenberg.org/files/78995/78995-h/78995-h.htm).
I would ask that if "ch" units are too new to be used, we get ebookmaker warnings just like with other new units (e.g. vw units). Otherwise the HTML processing that happens on PG's end should not remove lines with "ch" units.
