Hi,

Here is a recipe that makes characters typed into a bug report
invisible.

   - emacs -Q
   - M-x eww <RET> gnu.org <RET>
   - M-x report-emacs-bug <RET> foo <RET>

Now in the message buffer for the report, any character you type won't
appear.  A previous discussion with Eli on help-gnu-emacs shows that
this comes from an incorrect value of `text-property-default-nonsticky'.
