* @param [selector]

* Optional. A CSS selector for the elements to target. Default to

* Optional. Space-separated tokens which modify the default behavior.
|

* - `asap`: Try to remove the attribute as soon as possible. Default behavior
|
||||
* is to remove the attribute(s) asynchronously.
|
||||
* - `stay`: Keep trying to remove the specified attribute(s) on DOM mutations.
