Continuous memory growth in jco component

[ludfjig]

I have a simple wasm component compiled from the following js

export const handlerInterface = {
    handleevent(event) {
        return event;
    }
};

using jco componentize handler.js --wit ../component.wit -d all -o handler.wasm
with the following wit

package test:test;

interface handler-interface {
    record request {
        uri: string
    }

    handleevent: func(event: request) -> request;
}

world handler-world {
    export handler-interface;
}

I'm using wasmtime to call the handleevent guest function on the component in an infinite loop. It seems that RES memory of the process is constantly increasing over time, with no signs of stabilizing.
