LeElementSnippet not showing full content of columnedTree view inside it

[botwhytho]

Running this in an element snippet produces a columnedList view with no display issues:

((1 to: 12) asOrderedCollection gtItemsFor: GtPhlowEmptyView new)

Yet running the code below, which generates a columnedTree view cuts most of the content:

(((1 to: 42) asOrderedCollection collectWithIndex: [:n :i| n -> i]) asDictionary gtItemsFor: GtPhlowEmptyView new)
