I believe we've switched out all places that used to use the simple
isEmbedded() check to now use Platform.isSupported(ConditionalFeature.*)
checks instead.

In the case of ListView scrollbars, this code is handled in the
VirtualFlow class and checks (indirectly) the
ConditionalFeature.INPUT_TOUCH property for being true (in which case
the scrollbars are hidden when not in use).

I would suggest checking what you get when you call
Platform.isSupported(ConditionalFeature.INPUT_TOUCH).

Additionally, for your interest, you may want to check out some of the
other ConditionalFeature options. Here's some that may be of interest:

    /**
     * Indicates whether an on-screen virtual keyboard is used for text
input.
     * <p>
     * On embedded platforms JavaFX makes an attempt to initialize this
     * ConditionalFeature based on what input peripherals are attached. On
     * desktop platforms this ConditionalFeature will typically default to
     * false.
     * @since JavaFX 8.0
     */
     VIRTUAL_KEYBOARD,

    /**
     * Indicates whether or not a touch screen is attached to the device on
     * which JavaFX in running.
     * <p>
     * On embedded platforms JavaFX makes an attempt to initialize this

     * desktop platforms this ConditionalFeature will typically default to
     * false.
     * @since JavaFX 8.0
     */
     INPUT_TOUCH,

    /**
     * Indicates whether or not a touch screen providing multi-touch
input is
     * attached to the device on which JavaFX in running.
     * <p>

     * ConditionalFeature based on what input peripherals are attached. On

     * <p>
     * If INPUT_MULTITOUCH is available then INPUT_TOUCH is also available.
     * @since JavaFX 8.0
     */
     INPUT_MULTITOUCH,

    /**

     * mouse, trackpad or trackball is attached.
