[stumped]

so i have a poor quality text with many embedded spans, mid paragraph, like this:
part of paragraph text <span aria-label="page 17" epub:type="pagebreak" id="page_17" role="doc-pagebreak"></span> remainder of paragraph text

in calibre editor, sigil book view, ADE... they are harmless i.e. invisible.

so in fact i never noticed them until I began to read on Forma , and wondered why I was seeing so many "wrong", often mid sentence, paragraph breaks


it seems that on my forma, i get unwanted line breaks whenever such a span is encountered. i.e. the span is interpreted as a <br> , but is otherwise ignored

i am seeing this in a sideload from calibre, so dunno if its the extended driver , building kepub on the fly, that is struggling, or if it would also happen with a proper kepub source. [ the on-the-fly kepub conversion is not retained in calibre , I would have to look up how to capture a copy, in order to dig deeper

I do recall a similar thread ( but cannot find it now) where similar poor coding but with embedded anchors was causing a font size change on kobo.

i can, and did regex it all away, but what should a renderer do with such junk. Why is it NOT a problem on PC, but becomes a mess on Kobo.

is it the epub:type="pagebreak that is doing the damage, or would an embeeded span withonly a page_ID bit also mess up
