I can use Tooltip to show the value of each element in a ListPlot:

ListPlot[Table[Tooltip[a = Random[], a], {i, 1, 100}]]

but applied to QuantilePlot,

QuantilePlot[Table[Tooltip[a = Random[], a], {i, 1, 100}]] 

one gets a error message

QuantilePlot::ldata: 0.3164278757335126` is not a valid dataset, distribution, or a valid list of datasets and distributions.

and the return is not a plot but

QuantilePlot[{<numbers with tooltip when hovered over by mouse>}]

How can I work around this? I think it's a bug.
