Andreas Kling f79e28bd65 LibWeb: Break reference cycles so DOM::Document actually gets deleted 
When a document reaches ref_count==0, we will now remove all of the
descendant nodes from the document, and also break all the explicit
links (such as the currently hovered element.)

Basically, DOM nodes will keep the document alive even after the
document reaches ref_count==0. This allows JS wrappers to stay alive
and keep the document alive as well. This matches the behavior of
at least some other browsers.

This patch also adds a bunch of sanity checking assertions around
DOM teardown, to help catch mistakes in the future.

Fixes #3771.

SerenityOS

Graphical Unix-like operating system for x86 computers.

Travis CI status

About

SerenityOS is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.

Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by us, for us, based on the things we like.

I (Andreas) regularly post raw hacking sessions and demos on my YouTube channel.

Sometimes I write about the system on my github.io blog.

I'm also on Patreon and GitHub Sponsors if you would like to show some support that way.
