You can pass the { flush: 'sync' } option to recreate that behavior you want. This comment #1706 (comment) should be relevant to you

Thank you for response. Yeah, sync will be working.
But nevertheless, I can understand why there is no 2 logs per click, but it is weird that watch do not work at all after ref is changed. It means that it is forbidden to change watched ref in watch callback?

If it is expected behaviour, feel free to close the issue.
