Keep cursor centered in viewport upon toggling modals

Whenever you show or hide sidebars or e. g. the draft card, the text editor reformats, what makes sense. However, as the whole text shifts, you must scroll through the entire chapter again, looking for the section you were editing. This is a pain, especially in long chapters. It would be awesome if, whenever the text editor reformats, the text section that currently holds the curser would remain centered in the viewport.
