Commit [1] introduced a method to restore the mega menu state (closed)
so it's not saved open when saving the website builder edition.
That method is `_restoreMegaMenus()`.
It was then moved with commit [2], where it was called in `destroy`
where it was actually making the code crash because once you reach
`destroy`, the website content (the iframe) has already been reloaded
(and thus removed / recreated).
It's done through `reloadIframe()`.
So, depending of your network speed and the server response time, if the
page is served before reaching the mega menu restoration, it will crash.
Restoring the mega menu in the (wysiwig) destroy doesn't seems to do
anything as the page is already saved when reaching `destroy`.
Step to reproduce:
- Have a high latency, like 500ms (you can create a profile in chrome
debug tool in network tab)
- Create a mega menu on the website
- Enter edit mode
- Directly save or discard
-> Traceback, the jQuery toggle elements (`.o_mega_menu_toggle`) are not
in the DOM anymore, since the iframe got reloaded. Those elements
thus don't have a reference to `$` anymore, ultimately making this
line crash:
```js
const $toggle = toggle.ownerDocument.defaultView.$(toggle);
```
