OnTick is called multiple times every tick period

Describe the bug / error

Maybe this is a feature, not a bug, but why does OnTick result in multiple OnTick calls? An example can be seen here: https://github.com/tetratelabs/proxy-wasm-go-sdk/tree/main/examples/dispatch_call_on_tick.

Digging into it, NewPluginContext and OnPluginStart are called multiple times, which (I think) are creating multiple PluginContexts which leads to the issue. Why does this happen? I would expect OnTick to be called once every period.

Because it's created per worker thread. Please refer to the doc on how it works.
