Cannot create a widget whose initial state is visible=False

In ipywidgets 5.2.2 the code below produces a widget that is visible:

check = Checkbox(description="A box", visible=False)
check

In ipywidgets 4, the checkbox wouldn’t be displayed until I later set check.visible = True.

While this minimal example is pretty silly, I do rely heavily on being able to construct a widget with some components not visible until the user interacts with other elements.

A workaround or fix would be great.

Both title and select use the same instance of Layout, and both widgets are used twice (it shows the same Label and SelectMultiple twice, not copies). In short, all the (non-box) widgets have the exact same instance of box_layout. Try creating one layout for each widget (and probably multiple value widgets).

Can you post some code reproducing this?
