Persistent Storage - not supported in Chrome

[Bainainai]

What type of issue is this?

Other

What information was incorrect, unhelpful, or incomplete?

The persistent-storage permission should not be considered a working feature on Google Chrome.

A mechanism for obtaining the permission simply does not exist. It just returns false. It should not be considered a compliant feature.

What browsers does this problem apply to, if applicable?

No response

What did you expect to see?

Should not be marked as available.

Did you test this? If so, how?

I tried it on my own https domain, triggered from a user pressed button, and tried again by injecting code to do it through the F12 menu into a https://developers.google.com/ web page. Perusing the internet regarding this feature, it doesn't seem anyone has ever gotten it to work on Chrome.

Can you link to any release notes, bugs, pull requests, or MDN pages related to this?

Basically it is "supporting" a feature by just gracefully refusing any and all attempts to use the feature.
