Thanks for working on this! Could you also check if this approach works when the core tools are started by the Static Web Apps CLI? I'm afraid the terminal might not be TTY in that case, and would then not allow user interactions.

SWA CLI is used in many of our samples along with the Functions emulators, so this would still remain an issue.
