Strange, but, unless I misunderstood what your described, expected:

Reverting is a typical case where all local variable definitions are
cleared (intentionally): Unless arg PRESERVE-MODES is non-nil, this
calls `after-find-file' which calls `normal-mode' that (re)sets the
major mode of the buffer.  Changing the major mode typically always
kills all buffer local bindings.

So to say, it's a feature: `revert-buffer' also reverts local variable
bindings.


Michael.
