"breakpoints" command not listing breakpoints: "No breakpoints yet"

Hi, is this the upstream for what I describe below? :-)

main.js

#!/usr/bin/env node

function myfunc(i) {
  return i + 1;
}

let i = 1;
i += 1;
console.log(myfunc(i));

Start debugging:

node inspect main.js

Leaves me at:

Break on start in main.js:7
  5 }
  6 
> 7 let i = 1;
  8 i += 1;
  9 console.log(myfunc(i));

Now I set a breakpoint successfully:

sb('myfunc()')

but when I then run:

breakpoints

it just shows:

debug> breakpoints
No breakpoints yet

But help says: https://github.com/nodejs/node-inspect/blob/643179ef5e0452a52ceef2c5e7c8ca42ab00280f/lib/internal/inspect_repl.js#L57

Tested on node v14.15.3.

Reproduce the report with the provided main.js example using node inspect main.js, then inspect lib/internal/inspect_repl.js at the linked help entry and trace the breakpoints command. Done means a breakpoint set with sb('myfunc()') is listed instead of reporting “No breakpoints yet”.
