Hide/show button of expanded child elements does not work when editing container elements

[lsuma]

When editing a container element, changing the visibility status of an inline child element and then saving only works as long the child element has not been expanded yet. If it is already expanded or has been expanded once, the change is ignored.

Same here, is there any solution to Fix this?
