Illegal values in optional_permissions should be accepted

[piroor]

Describe the problem and steps to reproduce it:

Firefox now accepts illegal values in optional_permissions (after the Bug 1350759: Warn but accept illegal values in optional_permissions) but the linter still blocks any unknown permission names. Thus I cannot release my addon including new permission tabHide in optional permissions which is implemented at Firefox 59.

Steps to reproduce:

1. Create an addon including tabHide in its optional_permissions.
2. Upload it to AMO.

What happened?

I got 4 errors and couldn't release the version:

"/optional_permissions/2" should be equal to one of the allowed values

エラー: Your JSON file could not be parsed.
"/optional_permissions/2" should match some schema in anyOf

エラー: Your JSON file could not be parsed.
"/optional_permissions/2" should match pattern "^(https?|wss?|file|ftp|\*)://(\*|\*\.[^*/]+|[^*/]+)/.*$"

エラー: Your JSON file could not be parsed.
"/optional_permissions/2" should match pattern "^file:///.*$"

エラー: Your JSON file could not be parsed.

What did you expect to happen?

A new permission tabHide is warned but not reported as an error.

Anything else we should know?

(Please include screenshots and any relevant files.)

This is the file I uploaded.

Is this still reproducible for optional permissions?
