@JsonFormat(with = JsonFormat.Feature.ACCEPT_SINGLE_VALUE_AS_ARRAY) does not work on fields

Looks like JsonFormat.Feature.ACCEPT_SINGLE_VALUE_AS_ARRAY per-property override does not work, unlike its serialization counterpart (JsonFormat.Feature.WRITE_SINGLE_ELEM_ARRAYS_UNWRAPPED)

[cowtowncoder]

Oddly enough, while other features are supported, implementation for this (beyond exposing value for property) is missing. Due to extensive amount of changes needed, will only go in 2.7.

Was this ever fixed in 2.7? I'm still seeing this bug in 2.9.1

@dwybourn yes, as per check-in above and closing of this issue it should work.
If not, please file a new issue with reproduction -- I prefer not opening old issues since it makes tracking of fixes more difficult, even if the root cause is same or earlier fix was incomplete.
