Indeed.  After the recipe, "C-h l" shows this:

  <C-down-mouse-1> <drag-mouse-1> C-h l

What do you see on GNU/Linux?  Which toolkit(s) did you try it with?

FWIW, in the MSDOS build the problem doesn't happen, and view-lossage
shows just this:

  <C-down-mouse-1> C-h l

Any clue where could drag-mouse-1 come from?  I guess we don't discard
some events that we should.
