In (Xe)LaTeX it will be even worse because the natural width of a
\vbox is the line width. If such a \vbox appears in a paragraph just
after the footnote number, it will result in an overful \hbox.
Breaking the line between the footnote number and the \vbox is in
principle possible but the \hbox will be badly underfull and TeX will
not do it unless \tolerance is set to 10000. The problem is most
probably caused by the fact that tabular has zero height and positive
depth, it is probably set as \vtop. If placed inside \vbox, the
baseline of the \vbox will be aligned with the baseline of tabular,
thus the \vbox will still have zero height and positive depth (see my
example in one of my previous posts). Thus \vbox does not improve the
situation.
