Dark theme, can't see association lines

[BloodyIron]

I just tried the Dark theme, and while it makes the left and right sides Dark, it does not make the middle part Dark. However, it does make it so the lines that I would previously be able to see (lines with arrows) not actually visible now. So it's functionally useless.

Would be nice to get Darkness in the middle too, as well as seeing the arrows. Any chance we can get both please?

The themes are supported by diagrams.net themself so I think that any issues with them should be raised there. Their github page can be found here
