// We use this hook for the title field to automatically grow the height of the textarea.
// It helps keep the entire layout the way it is without having unnecessary scrolling and white spaces.
// Keep in mind this is what happens only here - in the Preact component.
// I'm mentioning this because the entire "Write a post" view is a preact component
// BUT it is also a classic .html.erb view which is being loaded BEFORE this component
// to give a feeling of blazing fast page load. And we do NOT use this magic autoresizing
// functionality on .html.erb view because there's no point of it.
