Not necessarily, no. It may consciously decide to hold on memory that
was used in the past in order to avoid having to re-allocate and
re-initialize it next time.
Some of that is simply "the cache", but there are all kinds of things
like that.
A leak would be if the amount of memory use increases each time you
visit a given page, even though that page always has exactly the
same content.
