import-globals-from
Parses a file for globals defined in various unique Mozilla ways.
When a /* import-globals-from <path> */
comment is found in a file, then all
globals from the file at <path> will be imported in the current scope. This will
also operate recursively.
This is useful for scripts that are loaded as <script> tag in a window and rely on each other’s globals.
If <path> is a relative path, then it must be relative to the file being checked by the rule.
Note: import-globals-from
does not support loading globals from ES modules.
These should be imported as variable definitions directly, or the file where
they are imported should be referenced.
