In creative mode, this isn't an issue since you have infinite items anyway, merely a cosmetic problem. This will therefore be closed, however rest assured that this bug and others related to inventory will be fixed in an upcoming inventory rewrite.

No problem, as long if you start with the inventory rewrite soon :)
