Hi all,

I found an annoying behavior of Firefox 148.0.2 in Windows, which might
be a bug. I'd appreciate a hint if I am missing something.

When printing (using Ctrl-p within the browser) a web page which
contains <details> elements, I would expect Firefox to print the
expanded <details> elements and show only the <summary> of the collapsed elements. This is what I observe using Firefox 140.8.0esr in Linux.

When using Firefox 148.0.2 in Windows, already in the print preview all elements are displayed, even when they are not opened on the web page.

Example: https://web.dev/learn/html/details
(at "Workshop reviews"). The triangle shows even in the print if the
element was originally opened or not.

Any opinions?

Regards,
Olaf

The example page I chose seems to not display the part with the
<details> tags in the print preview depending on the browser settings
for Java script etc. Therefore here a better (simplier) example page:

TYI: The behavior remained in 149.0. I filed a bug https://bugzilla.mozilla.org/show_bug.cgi?id=2026120

(In 149 printing got even worse: https://bugzilla.mozilla.org/show_bug.cgi?id=2026109 )
