/**
|
|
* Mark all elements on the page as inert, except for the ones that are allowed.
|
|
*
|
|
* We move up the tree from the allowed elements, and mark all their siblings as
|
|
* inert. If any of the children happens to be a parent of one of the elements,
|
|
* then that child will not be marked as inert.
|
|
*
|
|
* E.g.:
|
|
*
|
|
* ```html
|
|
* <body> <!-- Stop at body -->
|
|
* <header></header> <!-- Inert, sibling of parent -->
|
|
* <main> <!-- Not inert, parent of allowed element -->
|
|
* <div>Sidebar</div> <!-- Inert, sibling of parent -->
|
|
* <div> <!-- Not inert, parent of allowed element -->
|
|
* <listbox> <!-- Not inert, parent of allowed element -->
|
|
* <button></button> <!-- Not inert, allowed element -->
|
|
* <options></options> <!-- Not inert, allowed element -->
|
|
* </listbox>
|
|
* </div>
|
|
* </main>
|
|
* <footer></footer> <!-- Inert, sibling of parent -->
|
|
* </body>
|

* ```
