Reordering GtkColumnView with column separators messes up the separators
Any reorderable ColumnView with column separators will fail to present column separators correctly after moving one of the columns to the left and back. The leftmost column doesn't seem to exhibit this behaviour.
I couldn't find a ColumnView with separators in the demos, and unfortunately can't write C, so I wrote my SSCCE in Rust. If you can't bear to lay eyes on Rust, allow the following demo to entertain you instead:
(Note how the separator appears to be on the left side instead of the centre after moving!)
