 * Utility making it easy to add tooltips positioned on the editor's cursor. Before you
 * can show the tooltip, a {@link cursorPosition} extension must be added to the editor.
 *
 * This works by appending your tooltip to a flex container. You can style this container
 * with the selector `.pce-tooltip` if needed. This container is then added to the editor's
 * overlays. It also has `overflow-x: clip` to prevent your tooltip from overflowing in
 * browsers that support it.
 *
 * If you want your tooltip to always be visible when scrolling horizontally, you can add
 * `position: sticky` along with the `right` and `left` CSS properties to it.
 *
 * @param editor Editor you want to add the tooltip to.
 * @param element Element for the tooltip.
 * @param fixedWidth If false, the tooltip will shrink instead of getting offset to
 * the left if there's not enough space to the right of the cursor. Defaults to `true`.
 * @returns Show and hide functions.
 *
 * @example
 * const [show, hide] = addTooltip(editor, element)
