This issue was resolved in v3.3-beta-3:

(Sorry if this reopens the issue, I don't know how to use Github tbh, just doing this so that you can mark the issue as resolved.)

All good - hard for us to keep track of too :). We hold off on closing just to say 'too old', but it's more just a chance to reopen communications on what MIGHT be a stale issue - if you see something in the current release that looks like this, please feel free to reopen :)
