Vue version

3.5.12

Link to minimal reproduction

❌ NOT WORK minimal reproduction - 3.5.12
✅ WORK minimal reproduction - 3.5.5

Steps to reproduce

  1. Type g in the <input> element on the screen.
  2. Check the developer tools to see if run 1730889072865 (timestamp as of the current time) is logged.
  3. Delete g and re-enter g.
  4. Check the developer tools again; you’ll see run 1730889075430 logged once more. However, since this computed doesn’t track any reactive data, it should not be updating here.

What is expected?

2024-11-06.10.57.55.mov

When we roll back to version 3.5.5 and repeat the steps above, in step 4, checking the developer tools reveals that the computed does not recompute, this is the expected behavior.

What is actually happening?

2024-11-06.10.57.28.mov

The computed property recalculates each time the condition is toggled.
