Now it follows the same pattern as e.g., the document properties component, which allows us to have one instance of the find controller and set a new document to search upon switching documents. Moreover, this allows us to get rid of the dependency on `pdfViewer` in order to fetch the text content for a page. This is working towards getting rid of the `pdfViewer` dependency upon initializing the component entirely in future commits. Finally, we make the `reset` method private since it's not supposed to be used from the outside anymore now that `setDocument` takes care of this, similar to other components.
