Empty trailing fields ignored by read

When using a non-default IFS (a default IFS would trim them), a single
empty trailing field is ignored for read -a.

IFS=: read -rd '' -a arr < <(printf %s ':foo:bar:'); printf '<%s> '
"address@hidden"; echo
<> <foo> <bar>

I would expect the output to be:
<> <foo> <bar> <>
