Merge data from {@link Publisher} sequences provided in an array/vararg
into an ordered merged sequence. Unlike concat, sources are subscribed to
eagerly. Unlike merge, their emitted values are merged into the final sequence in subscription order.
This variant will delay any error until after the rest of the mergeSequential backlog
has been processed.
