These form components still use bootstrap CSS classes but are part of
our effort to move away from bootstrap.

Using :is-open="true" interferes with the dialogs close function in
nested dialogs.

This can be used in views to parse the error state from steering
responses.

We have properties like header, that contain objects that need to be
merged recursively.

Interfering with the default dialog close logic isn’t that smart because
it handles stuff like nested dialogs for us.

We need to find some other logic to close the dialog when someone clicks
on the backdrop, but that can be a task for a later time.

Using the same name as the native HTML dialog is a bad idea.
