Brightness Control and Target Key Menus latch open

We're running 3.2.9 build 16, reproducible on both Apex 10 and 5

When holding displays to open the brightness control and target key options, pressing either next or last will lock open both of these views when displays is released. Tapping the touchscreen closes brightness control, but displays needs to be held and released again to close the target keys options.

Is this a bug or expected behaviour?
