    I've checked with Unity 2019.3b10.

    Warning has gone, but as you wrote in change log of b10

    (UI: Values of sliders in the Inspector are now validated on Update rather than on Validate to avoid calling the Clamp function, which triggered a RectTransformChange)

    Clamp function is still here and executes unexpectedly.

    Clamp function here needs to be fixed.

    Tips: Check with different values of slider min & max & value with code.
    Use 2 different range to set in code (-8:8) and (-2:2). Switch between them and set different values with code. You will get wrong work of clamp function.
