-   * Adjust existing selection to select text within the original selection.
-   * - If `selectedText` is not supplied, we fetch selected text with
-   *
-   * ALGORITHM:
-   *
-   * MULTI-LINE SELECTION
-   * 1. Find line that contains `toSelect` text.
-   * 2. Using the index of this line and the position of `toSelect` text in it,
-   * construct:
-   *   * newStartLineNumber
-   *   * newStartColumn
-   *
-   * SINGLE-LINE SELECTION
-   * 1. Use `startLineNumber` from the current selection as `newStartLineNumber`
-   * 2. Find the position of `toSelect` text in it to get `newStartColumn`
-   *
-   * 3. `newEndLineNumber` — Since this method is supposed to be used with
-   * markdown decorators that are pretty short, the `newEndLineNumber` is
-   * suggested to be assumed the same as the startLine.
-   * 4. `newEndColumn` — pretty obvious
-   * 5. Adjust the start and end positions of the current selection
-   * 6. Re-set selection on the instance
-   *
-   * @param {string} toSelect - New text to select within current selection.
-   * @param {string} selectedText - Currently selected text. It's just a
-   * shortcut: If it's not supplied, we fetch selected text from the instance
