When the fluid of a super fluid makes the transition from a normal
state to superstate they climb up the walls of the container and will
climb out if not constrained. It takes really good seals on the
threads of the container to maintain confinement once the fluid
transitions. (These are closed vessel type experiments with secondary
external cooling.)
This result is so surprising and counter intuitive I have heard
several experimentalists comment on it.
If you would like to see a video that in part documents the effects I
am referring to you can follow this link.

It is perhaps possible that all observed effects are due only to the
transition to zero viscosity, but I have been told this question has
been examined and seems ruled out.
As for any measured change in mass, I'm sorry I but don't have a
published reference on this question. As I said, I do not know that it
has been publicly reported but I do believe it has been examined. The
following quotations from Wikipedia indicate the reality of the issue
and the references may indicate resources for further research in the
relevant literature.

Theories
L. D. Landau's phenomenological and semi-microscopic theory of
superfluidity of helium-4 earned him the Nobel Prize in physics, in
1962. Assuming that sound waves are the most important excitations in
helium-4 at low temperatures, he showed that helium-4 flowing past a
wall would not spontaneously create excitations if the flow velocity
was less than the sound velocity. In this model, the sound velocity is
the "critical velocity" above which superfluidity is destroyed.
(Helium-4 actually has a lower flow velocity than the sound velocity,
but this model is useful to illustrate the concept.) Landau also
showed that the sound wave and other excitations could equilibrate
with one another and flow separately from the rest of the helium-4,
which is known as the "condensate".
From the momentum and flow velocity of the excitations he could then
define a "normal fluid" density, which is zero at zero temperature and
increases with temperature. At the so-called Lambda temperature, where
the normal fluid density equals the total density, the helium-4 is no
longer superfluid.
Properties
Theoretically, a normal fluid phase of non-zero entropy can coexist
with a superfluidic phase with zero entropy. This leads to the strange
phenomenon of a two-fluid model, in which there can be a transfer of
mass without a transfer of energy: when such a fluid/superfluid system
is introduced in a setup that would normally trap a fluid, the
superfluid can flow out due to its zero-viscosity property, leaving
the normal fluid behind. Thus, part of the fluid system's mass is
transferred without any energy transfer (since the superfluid has zero
entropy).
Perhaps I should have said that superfluids do not respect the rules
of momentum and interia, instead of gravitation, but the
interconnectedness of these characteristics in classical mechanics is
well known and the disconnectedness of these characteristics in
superfluids is similarly well known.
