Cannot hide QSelect options dialog header with scoped css in Cordova App

[nulele]

Hello,
in my Quasar Cordova App, I have a component with a QSelect and I'd like to hide the options dialog header but cannot do it with the scoped attribute.

See the image for html structure

NOT WORKS

<style scoped>
  div.q-select__dialog >>> label {
    display: none;
  }
</style>

WORKS

<style>
  div.q-select__dialog label {
    display: none;
  }
</style>

Any idea?
Thanks

I think you should deep select q-select's class first. ie. v::deep.q-select__dialog label

Thanks but it doesn't work... Maybe I've already tried something like that.

Every time I re-build the app (in dev mode) to be super sure because I know hot reload is not trustable in this situation.
