Yes, I tried this with emacs -Q and I still experience the same
behaviour. FWIW, here's the output from view-lossage:

M-x h i g h l <tab> l i n <tab> <return> S T R O K E <return> <return>
M-x r e v e r t - b u f <tab> <return> y e s <return> M-x <up> <up>
<return> <return> <return>

I should also mention that I didn't modify the file before reverting
the buffer, so the contents were exactly the same.
