Vaadin 8.1 unable to set height for the Tree component

[Wnt]

Tree's setHeight methods have JavaDoc "This component's height is always set to be undefined. Calling this method will have no effect."

This makes it impossible for the developer to define where Tree's scrollbars are rendered to.

e.g. here I'd like to have the scrollbars on the bottom of the UI regardless of how many items I have in the Tree

Tested using Vaadin 8.1 SNAPSHOT vaadin-server-8.1-20170703.100423-235 & chromium browser on Linux

As a workaround one can extend Tree to override the non-working setHeight methods:

public class MyTree<T> extends Tree<T> {
	@Override
	public void setHeight(float height, Unit unit) {
		getCompositionRoot().setHeight(height, unit);
	}
	@Override
	public void setHeight(String height) {
		getCompositionRoot().setHeight(height);
	}
	@Override
	public void setHeightUndefined() {
		getCompositionRoot().setHeightUndefined();
	}
}

Thanks for the workaround
