style nit

If this is a continuation of shouldLimitLabelWidth, it should be aligned with
"If true, ..." above to make it clearer.  Seems like this would actually be
better to just be continuations on the animationDurationMillis comment though

If you want this to be separate, I believe it should go above the params and I
would put a blank line to split them up.

Done.
