Steps to reproduce

  1. Open the console in the playground
  2. Click on increase. See how in console the previous value is always undefined
  3. Switch to any Vue 3.4.x version (and reload the playground just in case)
  4. Repeat step 2. See how previous value is correct.

What is expected?

previous points to the old value

What is actually happening?

previous no longer works
