Ellipses lose all decorative features when 'invisible' overlay starts at a point where underlying text changes its 'face' property. |

I am able to reproduce this issue running emacs -Q with "GNU Emacs 24.3.50.1 (i686-pc-linux-gnu, GTK+ Version 3.6.3)".
I've wrote a snippet that will allow me to demonstrate this issue:
(let ((str (concat (propertize "red" 'face '((:foreground "red")))
(propertize "green" 'face '((:foreground "green")))
(propertize "blue" 'face '((:foreground "blue")))))
(printer (lambda (offset)
(let* ((pos1 (+ offset (point)))
(pos2 (+ 1 (length str) pos1)))
(insert str ?\s str ?\n)
(overlay-put (make-overlay pos1 (+ 3 pos1))
'face '((:inverse-video t)))
(overlay-put (make-overlay pos2 (+ 3 pos2))
'invisible 'outline)))))
(with-current-buffer (get-buffer-create "*test*")
(setq buffer-invisibility-spec '((outline . t)))
(text-scale-set 4)
(display-buffer (current-buffer))
(erase-buffer)
(mapc printer '(2 3 4))))
After running this code you will be able to see, in a new buffer, 3
lines of 2 words, all words are the same, each line features
three-letter long overlay over each of the words, highlighting letters
underneath them on left side, and hiding them behind ellipses on right
side.
Whenever an overlay spans from a point where there's a change to
'face' text-property, produced ellipsis doesn't adopt face decoration of
neither side. Furthermore, ellipsis part of the buffer appears to
ignore current text-scale setting, which is being set to 4 for temporary
buffer in my example.
Thank you for your attention.
All corrections that may help me improve my further reports are welcomed.

Hi, Eli,
I finally checked this and it is indeed fixed in master. Also, the
problem with ellipses not scaling together woth the text in Org-mode
(which I suspected was related to this) seems also to be fixed. That is
really great, thank you! I'm closing this bug.
Best
