    /**
     * Watch containers for size changes and ensure that Shiny outputs and
     * htmlwidgets within resize appropriately.
     *
     * @details
     * The ShinyResizeObserver is used to watch the containers, such as Sidebars
     * and Cards for size changes, in particular when the sidebar state is toggled
     * or the card body is expanded full screen. It performs two primary tasks:
     *
     * 1. Dispatches a `resize` event on the window object. This is necessary to
     *    ensure that Shiny outputs resize appropriately. In general, the window
     *    resizing is throttled and the output update occurs when the transition
     *    is complete.
     * 2. If an output with a resize method on the output binding is detected, we
     *    directly call the `.onResize()` method of the binding. This ensures that
     *    htmlwidgets transition smoothly. In static mode, htmlwidgets does this
     *    already.
     *
     * @note
     * This resize observer also handles race conditions in some complex
     * fill-based layouts with multiple outputs (e.g., plotly), where shiny
     * initializes with the correct sizing, but in-between the 1st and last
     * renderValue(), the size of the output containers can change, meaning every
     * output but the 1st gets initialized with the wrong size during their
     * renderValue(). Then, after the render phase, shiny won't know to trigger a
     * resize since all the widgets will return to their original size (and thus,
     * Shiny thinks there isn't any resizing to do). The resize observer works
     * around this by ensuring that the output is resized whenever its container
     * size changes.
