Even though it can be toggled via the 'hide' variable? Okay, will do!

Please peruse attached to reproduce another glitch that occurs with 
(setq org-hide-emphasis-markers t). The screencast illustrates what 
happens in the sample file. The glitch (the pointer automatically 
dropping to the line below a heading rather than staying at the far 
right of the heading) seems to occur only when point is on a line below 
the mouse click location (the mouse is clicked in the empty space to the 
right of headlines) and it does not seem to happen for headings with 
children.

I can reproduce, but I do not think that it is Org's bug.
I recommend you sending this reproducer to Emacs devs (M-x
report-emacs-bug).
