Is there something special you need to

Is there something special you need to do to get local Chrome DevTools profiling working properly? I'm trying the following (with wrangler 3.22.3): * wrangler dev -e test --port 8787 * push 'd' to open chrome devtools, which opens https://devtools.devprod.cloudflare.dev/js_app?theme=systemPreferred&ws=127.0.0.1%3A9229%2Fws&domain=(REDACTED)&debugger=true * Confirm source files appear under "Sources" tab * in devtools->Profiler, click start * send a request to the local port, confirm the request appears in the devtools network tab * stop profiling * All I see in the CPU profile is (program), without any detail on the actual function calls (see screenshot) * I get the same result if I try chrome://inspect` and then "Open dedicated DevTools for Node" (see 2nd screenshot)
