Dig command never ends

I installed the dig command with: apk add dns-utility. It runs but does not end (i.e., does not return to the command prompt).

Start by reproducing the reported command flow: install dig with `apk add dns-utility`, run `dig`, and observe whether it returns to the command prompt. The issue names no source files or tests; done means identifying the cause of the non-terminating command and adding a regression check for the corrected behavior.
