API dag "retry" POST request hangs until job completion

good day to you!

today I was playing with API and discovered that "retry" "action" post request hangs until the dag is not finished. The POST request hangs and if the job runs longer than the default request timeout (e.g. 30 sec) - the request fails.
i'd expect it to restart the dag and return 200 code back and not wait until finished ;)

Is this a bug?

P.S. v1.13.0

regards
