I'm now sure what's this is about.  Clicking any links (with mouse-1) in
the *Help* buffer here dings my Emacs, and this is the backtrace I'm
getting if I instrument `ding':

Debugger entered--entering a function:
* ding()
  pop-mark()
  #f(compiled-function () #<bytecode 0xb41ff211354d205>)()
  #f(compiled-function () #<bytecode 0x1b178ae04d6865b2>)()
  clear-transient-map()

I don't have a recipe to reproduce it, though -- In this Emacs I can do
`M-x describe-face RET default RET' and then mouse-1 on the "faces.el"
button, and Emacs will ding me before taking me to the faces.el file.
