The simplest solution I could come up with was to make quitting the app asynchronous. Calling mac::Platform::quit enqueues a request to quit the app and then allows the call stack to fully return. This ensures we aren't holding a borrow when we quit and invoke all the Window::on_close callbacks. Seems like it should be fine to be async on quitting.
Call on_focus on the root view when the window is originally created. Test dropping a focused view. Simplify test to avoid relying on emitting events.

This allows us to spawn long-running tasks without leaking entities, but it also ensures that if we *do* hold on to a task, that the entity exists until the future or stream complete so that the task doesn't need to return an Option type.

This way, if we create and drop a handle during the creation of a view, we don't drop the view before we have a chance to increment its initial reference count.

Instead, store all views in a single top-level map that's keyed by window id and view id. This ensures we'll keep a view alive even if its window is gone, so long as we're holding a handle. This can happen with things like spawned tasks. We don't want to panic during a spawned task after we close the window.
I didn't realize a previous change had broken stuff. We need to always call `remove_dropped_entities` and `update_windows` in `flush_effects`, even if there aren't any effects. To achieve this, I use a `loop` to ensure we call these methods at least once before breaking.
This ensures that we correctly update the hover state of elements whose position has changed relative to the mouse cursor even though the mouse hasn't actually moved.

It returns a future that resolves when the provided predicate returns true. The predicate is called any time the handle's targeted entity calls notify.
Still need to add a timeout and completely remove finsih_pending_tasks.
* Enforce a min width per tab
* Center the title within tab, regardless of icon
* Render icon over the top of the tab title
* Ensure there is always a fixed minimum amount of filler to the right of all tabs
