What is the behavior of the dynamically import function

[imzlh]

I'm trying to dynamically import a JS module

if(!import.meta.path || self.entry == import.meta.path){
    const file = self.argv[0];
    if(!file){
        throw new Error('Expect an arg to run test');
    }
    console.log('Start test:', file, '\n');

    try{
        const path = (import.meta.dirname || self.dirname) + '/' + file + '.js';
        console.log(path);
        import(path);
        delay(10000);
    }catch(e){
        console.error('Could not load test:' + file, e);
    }
}

However，the promise never come fulfilled，while the follow one works

import * as test from "./test.js"

And the follow example will block the whole program infinitely

await import(path);

The key function that would affect this is "JS_ExecutePendingJob", however, I am confused about its role.
I would appreciate it if someone could tell me its role.

Please paste a full script that exhibits the problem.

Call JS_ExecutePendingJob(ctx, &ctx1) in a loop, or call js_std_loop(ctx) when your program calls js_std_init(ctx, m).

You can find examples of how to use both functions in this repo.
