Nice! I’ve found a little flaw: When set the dialog to draggable with setDraggable(true) opening the details after dragging the dialog does not resize the footer.
Hmm, I don’t think this is something I can control. It seems when the underlying Vaadin dialog is dragged, its position and size are “frozen”. Up to that point it would automatically resize and recenter according to its content. I don’t see anything in the Java API that could help like a listener for dragging.
I created a ticket for the vaadin-dialog component.
