> Affects Versions: 1.18.0, 1.17.2

> FLINK-21945 will convert the unaligned checkpoint barrier and timeoutable
> aligned checkpoint barrier to force aligned barrier. However, Force aligned
> barrier logic doesn't work for timeoutable aligned checkpoint barrier.
>
> Bug at
> org.apache.flink.streaming.runtime.io.RecordWriterOutput#broadcastEvent, we
> will call withUnalignedUnsupported to transmit the unaligned checkpoint
> barrier to {color:#9876aa}FORCED_ALIGNED {color}barrier when the shuffle type
> cannot use unaligned checkpoint.
> However, the if has one condition: isPriorityEvent. When aligned checkpoint
> timeout is enabled, flink will emit one timeoutable barrier. It isn't
> PriorityEvent.
>
> But timeoutable barrier should call withUnalignedUnsupported here.
