[stumped]

i posted a separate thread about this same issue- it had GIGO but in the title
depending on what is an an embedded span or anchor, the forma will render a line break, or will change text size or both.
v annoying. I do use the extended driver to sideload as kepub so maybe that is the cuplrit
sample para
<p class="Text-Standard-tx">“You ordered a shuttle through deception,” bubbled the marshal of Drearburh, whose main claim to fame was that he was more <span aria-label="18" id="pg_18" role="doc-pagebreak"></span>decrepit alive than some of the legitimately dead. He stood before her on the landing field and gurgled with indignation. “You falsified documents. You stole a key. You removed your cuff. You wrong this house, you misuse its goods, you steal its stock.”</p>
class CSS for that is
p.Text-Standard-tx {
font-size:0.858em;
font-style:normal;
font-weight:normal;
margin-bottom:0em;
margin-left:0em;
margin-right:0em;
margin-top:0em;
text-align:justify;
text-decoration:none;
text-indent:1.2em;

after the span is rendered , the font size is INCREASING, until paragraph end.
