Describe the bug
When the app switches to Dark mode, all the connection arrows disappear. They are still there because I can "select all" and I see them, but they are invisible. If I turn off Dark mode, they are visible (black).

To Reproduce
Steps to reproduce the behavior:

1. Start in "light" mode
2. Create several shapes
3. Connect them with connection arrows (they will be black arrows)
4. Switch to "dark" mode and notice that the arrows are gone

Expected behavior
The connection arrows should be there in both "light" and "dark" modes
