An interesting question is why this leakage current is felt only when the
finger is moved across the surface, and not at all (or in some cases less
so) when pressing in one place.

I suspect it might that the leakage current, as small as it is, is actually
relatively high for the cross section it is passing through when the touch
is very light.  It is a high cross sectional current, causing very small
amounts of tissue to react to it.  Thus the feeling is not painful, but is
usually obvious.

I feel it very readily, but have known people who touch when I do and cannot
feel it at all.

I one piece of equipment, I readily felt it very often.  One day I accidently
touched something else while touching it... ***ZZZZZAP***.  I found it had one
side of the AC connected directly to the chassis.  Although an isolation
transformer would have cured it, I chose what happened to be for me the less
costly approach: I scrapped it for parts.
