Yes, adding `transform-style: inherit` into `-moz-table-wrapper` makes everything disappear. And got an assertion if I add `transform-style: inherit` into `-moz-cell-content`.

One thing to note: WebKit may also have something wrong in the similar cases. It doesn't pass the wpt, and have some strange behaviors if the combined rotateX() is more than 90deg. (Not sure what happens. It looks like Gecko has the similar behavior.)

Besides, in the frame tree, I notice `TableRowGroup(tbody)` doesn't have `combines-3d-transform-with-ancestors`. This may be a hint that it doesn't combine its 3d context with its ancestor. Need to dig deeper anyway.

UPDATE:
It looks like `preserve-3d` doesn't work on table element. `IsExtend3D()` always return false because `mTransoformStyle` is always flat, even if we set the style to `preserve-3d`. I tried to hack it to make it return true in this function, but the element inside the table disappears, just like bug 1560704.
