'wait' program does not wait

[Alexey Gladkov <gladkov.alexey@xxxxxxxxx>]

Greetings!

'wait' does not wait for all jobs and return a non-zero exit status.

According dash(1):

wait [job]
Wait for the specified job to complete and return the exit status
of the last process in the job. If the argument is omitted, wait
for all jobs to complete and the return an exit status of zero.

$ cat test.sh
#!/bin/dash
func() {
	sleep $1
	echo "func($1)"
}
func 1 &
func 2 &
func 3 &
wait

$ dash ./test.sh; echo "after rc=$?"
func(1)
after rc=145
func(2)
func(3)

$ bash ./test.sh; echo "after rc=$?"
func(1)
func(2)
func(3)
after rc=0
