How to replicate

1. Go to https://glimmer-complete-source.glitch.me/
2. Click Button 1, then Button 2
3. Wait a few seconds
4. Check the DevTools console

The first button starts two timeouts, the second button just blocks the CPU right away.

What should happen

web-vitals.js should report the button click handler LoAF script in the INP attribution data.

What happens instead

I get this in the logs:

Interaction from 2090 to 4946
INP LoAFs
1910 - 3910: TimerHandler:setTimeout
LoAFs
1910 - 3910: TimerHandler:setTimeout
3910 - 4910: BUTTON#button-2.onclick
4910 - 6910: TimerHandler:setTimeout

Even though the onclick LoAF script runs during the interaction, it is not included in the attribution LoAF data.
