Jelle Raaijmakers 2e1320f264 WindowServer: Reevaluate hovered window on window rect change 
When a new Window instance is added to the WindowManager, it does not
yet have an updated value for `m_frame->rect()` and we're not checking
if there is a new candidate for the hovered window, which we need to do
since the mouse cursor might hover above the newly opened window.

This fixes both issues: as soon as a Window frame's rect is changed,
ask the WindowManager to reevaluate its hovered window. This takes care
of newly opened windows _and_ windows that are programmatically changed
in size.

This works because when a Window becomes hovered, the WindowManager
sends out an enter event. This event in turn triggers the Window to
evaluate the cursor type under the mouse position and to update it when
necessary.

Fixes #4809.

SerenityOS

Graphical Unix-like operating system for x86 computers.

Build status Fuzzing 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.
