macOS: Assertion fails when closing `{httpuv}` server

[Barret Schloerke]

Example: https://github.com/rstudio/httpuv/actions/runs/4911951339/jobs/8770464750#step:4:152

Probable failing assertion:

httpuv/src/libuv/src/unix/core.c

Line 259 in faada3a

 assert(!(handle->flags & UV_HANDLE_CLOSED)); 

Reprex: Start shiny app then close app. Error is thrown and R session is killed
