Loading two microapps with { singular: false } doesn't work

What happens?

I have one master app and two micro apps that I want to load on same page.

I see only one loaded:

My template:

<div id="container">
    <h2>App 1 container:</h2>
    <div id="app1Container" />
    <h2>App 2 container:</h2>
    <div id="app2Container" />
  </div>

apps passed to registerMicroApps:

apps: [
   { name: 'app-1', entry: '//localhost:8082', container: '#app1Container', activeRule: () => true },
   { name: 'app-2', entry: '//localhost:8083', container: '#app2Container', activeRule: () => true },
]

and starting like this:

start({ singular: false })

You could never guarantee your project name is unique, while you could not know who will be migrated into the same master app with you.

Usually a child application doesn’t know whether they are unique or not, as they are not aware of each other, and it shouldn’t care imo.
