[BUG] odt export of 'utf-8-with-signature-unix' file is 'corrupt' [9.6.15 (release_9.6.15 @ /usr/local/share/emacs/29.4.50/lisp/org/)]

I want to export a document with a different encoding to ODT. The file
has a buffer coding system of 'utf-8-with-signature-unix' and exports to
other formats, such as HTML, well. No errors occur when exporting to
odt, these are all the messages that are printed:

However, when opening with LibreOffice, the file needs to be 'repaired'
because it is 'corrupt'. Converting to pdf with libreoffice --convert-to
pdf also fails silently and does not produce a pdf.

Changing the buffer coding system to 'utf-8-unix' exports as expected.
