Commit [1] fixed the editor not being able to start when clicking on a
link that triggers a download. This was caused by the
websiteRootInstance being undefined when a page is about to be
unloaded (beforeunload). Unfortunately, this event can be canceled.
This means that the websiteRootInstance had to be undefined when we are
certain that a navigation is going to happen within the iframe. However,
the condition introduced by [1] does not take into account multiple
factors, which lead to the websiteRootInstance being undefined during
edition.
This commit fixes that and introduces a test to make sure this behaviour
is not easily broken again.
Steps to reproduce:
- In edit mode, on the Home page, go in the footer and click on any link
(except "Contact Us") under "Useful Links" or on the house icon in the
Social Media snippet.
- Change the footer height with the Height option.
=> The option is applied correctly (because the link stays on the same
page).
- Click on "Contact Us" or another Social Media icon.
- Try to change the footer height again.
=> The preview works but when we leave it, we see that the option was
not applied.
- Drop a snippet and click on it.
=> Infinite loading.
