Slide transitions can misjudge final dimensions - workaround should be documented

[clinkingdog]

Sometimes slideDown, slideUp and slideToggle events can misjudge the final dimensions of the page, and hence slide the element too far or not far enough - leading to a "jump" into the correct position at the end of the slide transition.

This can be worked around by an explicit height or width specification on the element in question, and it would be helpful if that workaround was documented on these methods.
