I believe this to be a bug, however, when setting the slider component to disabled, I am still able to move the slider and change values - the only change that happens is a visual change from the normal state to the greyed out "Disabled" state
Edit: Appears this is being caused by the disabled condition being dependent upon a bool variable. If the variable is initialized as true, changing it to false will cause what was initially described. if the variable is initialized as false, the opposite effect will happen. The component will be initially rendered as disabled and the slider will be unable to move, however, on attempting to enable it (using a checkbox) the slider appears in the "Enabled" state, yet acts as though it is disabled
