inconsistent poll_oneoff behavior

[peter-jerry-ye]

Describe the bug
The poll_oneoff returned a clock event that has not yet finished

To Reproduce

I attached the poll.wat at the end

wasm-tools parse poll.wat -o poll.wasm
wazero run poll.wasm
wasmtime poll.wasm

Expected behavior
The program does not panic, that is the returned result array should have length of 1 instead of 2

Screenshots
N.A.

Environment (please complete the relevant information):

• Go version: N.A.
• wazero Version: 1.9.0
• Host architecture: Mac Arm 64
• Runtime mode: compiler
