isToolsShown parameter doesn't disable toolbar on initial load when set to false (on mdx Meta tag)

[Gideon28]

When updating from Storybook 5.3 to 6, our setting on the introduction page to hide the toolbar doesn't work. Navigating to other documentation pages and returning correctly removes it, but a refresh confirms that this isn't the case on first load.

To Reproduce
Steps to reproduce the behavior:

1. In preview.js we have added a parameter with options: isToolsShown: true (so that the toolbar re-appears unless otherwise disabled).

import { addParameters } from "@storybook/react";

addParameters({
  ...
  options: {
    ...
    // Toggle toolbar on by default - override per story if unwanted
    isToolshown: true,
  }
});

2. Our intro.story.mdx sets this parameter to false on the Meta tag from addon-docs, i.e.

import { Meta } from "@storybook/addon-docs/blocks";

<Meta
 title="Documentation/Introduction"
 parameters={{ options: { isToolshown: false } }}
/>

3. The introduction page loads initially with the toolbar visible, until navigating around produces the expected behaviour.

System:

• React 16.13
• Storybook 6.0.3
• Addon-docs 6.0.3

@shilman do you know if this is truly fixed? I still seem to be getting this issue, though subsequent load it is gone? Preview.js features:

options: {
    isToolshown: false,
