Actually, it is NOT fixed.
Following the original recipe, it is easy to see the bug:

I see all of the reported problems!
I pressed SPC to see the MIME part header, then clicked on it, and
moved the mouse over the expanded attachment text to highlight it,
I then pressed SPC a couple of times to scroll the buffer, and pressed DEL
to get back to the MIME header - and clicked it .. and the last line
is shown three times.
And there are lots of mouse-highlight artifacts.
This is probably a problem with scrolling through multiline
mouse-hightlight which spans multiple pages.
Chong, could you take another look at it?
