It's been that way since 7.2, and was intentional. IIRC, the array
parser's behavior in 7.1 and before was inconsistent across datatypes,
and we concluded this was the closest we could get to backwards
compatibility while still having something moderately sane. It is
documented:
You may write whitespace before a left brace, after a right
brace, or before any individual item string. Whitespace after an
item is not ignored, however: after skipping leading whitespace,
everything up to the next right brace or delimiter is taken as
the item value.
