Dark mode multiplicity barely visible in PDF

Hello,

When exporting to PDF using dark more, the colours of tables, lines and multiplicity numbers are preserved, but not the background. Multiplicity numbers are light grey, which makes then quite difficult to see, especially when using a lower-brightness screen or when printed. Would it be possible to preserve the dark theme when exporting to PDF except the multiplicity numbers, i.e. turning them back to black?

Thank you
