Animating visibility breaks the display type of elements.

[lhunath]

While .toggle(); correctly preserves the element's display type, animate(height: 'toggle'); for instance, does not.

In fact, in 1.4 it seems to be that the display type is first set to "block" for the duration of the animation and then reset to the correct display type.

See test case at: ​http://stuff.lhunath.com/jquery-tbody-block.html

This breaks the layout of my tables as block obviously renders differently than table-row-group.

Completely unusable for table rows spanning more than a row, for instance.
