odd array `collapse` behaviour with `groupArraysAfterLength`

[clausreinke]

Consider an object containing an array: {ARRAY: [...Array(n)], ...otherfields}, with collapse={1}.

• as long as n is smaller than groupArraysAfterLength, ARRAY collapses as expected
• as soon as n ist larger than groupArraysAfterLength, ARRAY is expanded (to collapsed groups)

I would have expected ARRAY to remain collapsed, no matter its length, with groupArraysAfterLength only taking effect after ARRAY is expanded (manually, or by raising collapse to 2).

With a large number of groups in ARRAY, this can be a problem, as there seems to be no way to really collapse ARRAY (short of setting groupArraysAfterLength={0}, which collapses ARRAY but leads to an unwieldy view when ARRAY is expanded).
