I have a question. I saw in spec operation HostMakeJobCallback, it describes two cases with non-null and null active script. Also there are two examples with code:

• active script is non-null

  Promise.resolve('import(`./example.mjs`)').then(eval);
  

• active script is null

  <button onclick="Promise.resolve('import(`./example.mjs`)').then(eval)">Click me</button>
  

I am interested in first one example. Imagine the following structure:

• index.html
• modules/
  • a.js
  • example.js

index.html

<script type="module" src="modules/a.js"></script>

example.js

console.log("example.js is included")

a.js (don't run with all cases together)

/// case 1
eval('import(`./example.js`)'); 

/// case 2
Promise.resolve("import('./example.js')").then(eval)

In case 1: eval won't throw an error and it will print "example.js is included". That I think will be correct because import gets GetActiveScriptOrModule() that will be Module Record

In case 2: then(eval) will throw the error. And for some reason this code will think that baseURL is "http://127.0.0.1:5501/" but not the "http://127.0.0.1:5501/modules"

Why these cases are different? Doesn't HostMakeJobCallback save active script for the future restoration with his baseURL from module script?

eval('import("./example.js")');

Promise.resolve("import('./example.js')").then(eval)
