A br inside a strong tag gets converted incorrectly

[Barsonax]

When converting html to markdown inserting a <br> inside a <strong> results in incorrect markdown:

Input

<strong>OK zu nicht bestätigtem Fehler <br></strong>

Output

**OK zu nicht bestätigtem Fehler  
**

Correct Output

**OK zu nicht bestätigtem Fehler**

Seems like a problem in the commonmark/gfm writer... as it works for -t markdown, right?

Also seems to be broken: https://pandoc.org/try/?text=%3Cstrong%3EOK+zu+nicht+best%C3%A4tigtem+Fehler+%3Cbr%3E%3C%2Fstrong%3E&from=html&to=markdown&standalone=0

but that's correct, backslash followed by newline is pandoc-flavoured markdown for <br>, see https://pandoc.org/MANUAL.html#backslash-escapes

But it causes the closing ** to end up the wrong line right?

It should be like this I believe:

Wrong:

**OK zu nicht bestätigtem Fehler\
**

Correct

**OK zu nicht bestätigtem Fehler**\

[mb21]

well.. that would be kind of nicer for a human to read, but it's not exactly the same content anymore...

**OK zu nicht bestätigtem Fehler\
**

converts perfectly fine back to the same HTML:

<p><strong>OK zu nicht bestätigtem Fehler<br />
</strong></p>

Ok then it seems only the github flavored version is broken: https://pandoc.org/try/?text=**OK+zu+nicht+best%C3%A4tigtem+Fehler%0A**&from=gfm&to=html5&standalone=0
