[Bug]: non-inline stories do not receive updates from controls for Docs pages

[quantizor]

Describe the bug

There appears to be a bug where a docs page that contains a non-inline primary story does not receive arg changes from the related <Controls /> panel.

To Reproduce

Visit a Docs page for a component and set the story parameters as follows:

docs: {
  story: {
    inline: false,
  },
},

This triggers the story to load inside an iframe instead of inline. When this config is set, manipulating the controls for the story has no effect.

System

No response

Additional context

Does occur in v6 as well when inlineStories: false

[quantizor]

I'm wondering if it's because the ID for iframe stories has the "iframe--" prefix?
