UnregisterBehaviour bug

[toczekmj]

Hi.
Today I've experienced weird bug related to overwriting existing selection behavior.
Our app seems to work fine while using default settings (example below)

Working.edited.-.Made.with.Clipchamp.mp4

But when we overwrite selection behaviour either with the default one, or with custom implementation, cards starts to behave unexpectedly. Namely in order to move a particular card we need to double click it, otherwise previously selected card is being moved. Example below:

Not.working.edited.-.Made.with.Clipchamp.mp4

This os our diagram configuration (working version, without overwriting default behavior)

var options = new BlazorDiagramOptions
        {
            LinksLayerOrder = 10,
            NodesLayerOrder = 10,
            AllowMultiSelection = true,
            Zoom =
            {
                Enabled = true,
                Minimum = 0.3,
            },
            Links =
            {
                DefaultRouter = new NormalRouter(),
                DefaultPathGenerator = new SmoothPathGenerator()
            },
        };

        var diagram = new BlazorDiagram(options);

And this is the overwriten version:

var options = new BlazorDiagramOptions
        {
            LinksLayerOrder = 10,
            NodesLayerOrder = 10,
            AllowMultiSelection = true,
            Zoom =
            {
                Enabled = true,
                Minimum = 0.3,
            },
            Links =
            {
                DefaultRouter = new NormalRouter(),
                DefaultPathGenerator = new SmoothPathGenerator()
            },
        };

        var diagram = new BlazorDiagram(options);
        diagram.UnregisterBehavior<SelectionBehavior>();
        diagram.RegisterBehavior(new SelectionBehavior(diagram));

It seems like some event is not being disposed while unregistering the behavior, but we really have no idea what is going on. Hope someone will help us.
