    # Locates a Trix editor and fills it in with the given HTML.
    #
    # The editor can be found by:
    # *   its `id`
    # *   its `placeholder`
    # *   the text from its `label` element
    # *   its `aria-label`
    # *   the `name` of its input
    #
    #
    # Examples:
    #
    #     # <trix-editor id="message_content" ...></trix-editor>
    #     fill_in_rich_textarea "message_content", with: "Hello <em>world!</em>"
    #
    #     # <trix-editor placeholder="Your message here" ...></trix-editor>
    #     fill_in_rich_textarea "Your message here", with: "Hello <em>world!</em>"
    #
    #     # <label for="message_content">Message content</label>
    #     # <trix-editor id="message_content" ...></trix-editor>
    #     fill_in_rich_textarea "Message content", with: "Hello <em>world!</em>"
    #
    #     # <trix-editor aria-label="Message content" ...></trix-editor>
    #     fill_in_rich_textarea "Message content", with: "Hello <em>world!</em>"
    #
    #     # <input id="trix_input_1" name="message[content]" type="hidden">
    #     # <trix-editor input="trix_input_1"></trix-editor>
    #     fill_in_rich_textarea "message[content]", with: "Hello <em>world!</em>"
