view-last-noparam not working for parameters embedded in a form submit

[Bruno Busco]

Hi,
it seems that the view-last-noparam just works (resets the parameters) if it
is used with a request that has the parameters in the URL.

Since we have now moved to form submitted parameters I found that the
view-last-noparam is not able to remove the parameters from the context.
Does anyone have any idea of how to fix this?

Thank you,
Bruno
