Typescript - Error: Property 'value' does not exist on type 'Option'. Did you mean 'valueOf'?

Started getting this error with 10.3.0. I believe the culprit is 1b04c15, which isn't in the changelog. Was it included intentionally?

[janosh]

can you provide a repro? either a Svelte REPL or a code snippet? i don't see how 1b04c15 would have caused this

My mistake, the error's gone now. I must've had something inconsistent

[erezarnon]

Actually, the error is still there. He's a minimal example

<MultiSelect
  options={[{value: 'abc', label: 'abc'}]}
  on:add={(event) => {
    // if you want to persist new user entered custom options to a database, perform
    // a fetch request with type POST here using the event.detail.option payload
    console.log(event.detail.option.value)
  }}
/>

the error doesn't repro for me. i pasted your snippet into a REPL and tried with versions 10.2.0 and 10.3.0. both work fine.

It's a typescript error. Is there a way to get typescript into that REPL?

[janosh]

sorry should have paid more attention to the issue title. the REPL doesn't support TS. but i can repro the type error. not sure what changed, needs some investigation (and better tests for the future)
