Thanks for the answer.

I think it'd be great to update that paragraph in the spec [1] to tell
not only what's not the first formatted line, but what's actually the
first formatted line in that case.

There's a similar example for ::first-letter [2] that has a clearer
wording:
"Thus, in <DIV><P STYLE="display: inline-block">Hello<BR>Goodbye</P>
etcetera</DIV> the first letter of the DIV is not the letter "H". In
fact, the DIV doesn't have a first letter."

Bye,
