It seems like after the refactor of the Splitter component in v5.2 it is not possible anymore to adjust the panel's min/max properties after init with useSplitter. This is needed if you want to have, let's say min: 20 / max: 80 in an open state, and a fixed width collapsed state with a lower value than that and control it programmatically to adjust for window size changes.

It would be great if the items in splitter.getItems() would expose methods like setMin / setMax or something like that.
