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).
