Incorrect (?) initial vPos with slideDown effect

[Man4x]

Studying the code, I think I saw that starting vPos for a slideDown-effected popup was its ending vPos minus its height. But if popup height is quite small and/or window height quite big, popup's bottom is visible when starting sliding down effect and then, effect is not a full sliding down (i.e. from out-of-screen to screen) anymore.
But maybe this is a normal behaviour for you.
In any case many many thanks for this beautiful tool.

I have this same issue and I think this is not normal. The "slide-down" effect should have been complete, without disappearing on the process.
