Blazor RenderTreeBuilder builder Resize

Question

im trying to bind the "resize" eventlistener to my component. I dont know why but it isnt working for me.

public event Action SizeChangedAction;

builder.AddAttribute(5, "resize", SizeChangedAction);

OnMouseUp OnClick everything working fine.

builder.AddAttribute(GetSequenceIndex(), "onmouseup", EventCallback.Factory.Create(component, component.OnMouseUp.InvokeAsync));

Does someone know how to get this working?

The "resize" event isn't a supported bindable event in Blazor, it's a JavaScript event.

There have been some attempts to write size event handling code, see https://github.com/EdCharbeneau/BlazorSize as one example.
