editor = editor in Svelte example

[JosephASullivan]

Hi all! Thanks for this great tool :)

I am setting up a new project using Tiptap and Svelte. I used this template from the Tiptap docs to get started. I am curious about this section:

onTransaction: () => {
        // force re-render so `editor.isActive` works as expected
        editor = editor
      },

Can someone explain to me what this does, and what would happen if you removed it? I have tried removing it and it doesn't seem to affect the functionality of editor.isActive (or anything else that I am seeing). Understanding why this is important would be very helpful to me so that I can (a) modify/rewrite it as necessary and (b) effectively test whether any modifications preserve its intended functionality.

Just giving this a gentle bump to see if there is anyone who can weigh in on this. Thanks!
