Invalid array length error with 1.21.2

[ggascoigne]

v 1.21.2 is giving me an Invalid array length error, reverting to 1.21.1 fixes it. I can't say that the stack is particularly helpful but perhaps it contains some clue.

I'd guess it's related to #336 - if an object has more than groupArraysAfterLength keys, it would be rendered as an array, I think.

Easy step to reproduce: add groupArraysAfterLength={1} to the first example in the dev server.
