If you playtest in the repro place the LocalScript under the BoxHandleAdornement with its Adornee to the Baseplate never prints BoxHandleAdornment Clicked if you click with your left mouse button despite the Active property being false on the TextButton. Whilst the TextButton always receives input, as it will always print “TextButton Clicked”

Expected behavior
I would expect both the BoxHandleAdornment and TextButton to recieve the input, as the TextButton has its Active property set to false.
Because this is what the docs say, and the Active property does work correctly when used on a Frame (and probably other GuiObjects).
