Transition leaves empty style element

[Restorn]

Describe the bug

Introduced in #7114

The current version clears the stylesheet and removes reference to it but leaves the empty style element behind.
Every transition creates a new style duplicate.
Previous version kept stylesheet reference as a part of the document.

Note that this is a memory leak for all intents and purposes, so any long-running app that is heavy in transitions will pile up empty tags rather quickly.

Whoever is prioritizing issues in this project might want to consider bumping the priority up a notch :)

My pull request got approval for running workflows, but many of them failed during the install-step because of a weird type error. I have no problem finding out what caused the type error, but i need help from a maintainer to run the workflows again.

It feels weird that this bug has been part of Svelte so long.
