I'm therefore also closing this bug.

If 'mouse-face is put on a reaion including linebreaks and active,
the appearance of the blank areas right to linebreaks is changed.
But pointing the blank areas does not activate 'mouse-face.
If 'mouse-face is put on a region ending with a linebreak,
the activated appearance covers the first character of the next line.
Example:
Evaluating the form below, a green area is displayed, where 'face,
'mouse-face, 'keymap and 'help-echo properties are put.
The green area includes a text "TARGET" and a blank area.
When pointing "TARGET", 'mouse-face is active.
The red area covers "*" in the next line, which has no properties.
When pointting the green blank area, 'mouse-face is not active.
Clicking the green area(both "TARGET" and the blank area) shows a
message "mouse-face: (:background red)".
The keymap is also active at "*" in the next line, which has no
properties.
The 'help-echo property is active only when pointing on "TARGET", not on
the green blank area.
(let ((map (make-sparse-keymap)))
(switch-to-buffer (generate-new-buffer "tmp"))
(define-key map [down-mouse-1] #'ignore)
(define-key map [mouse-1]
(lambda (ev)
(interactive "e")
(let* ((p (posn-point (event-end ev)))
(prop (get-text-property p 'mouse-face)))
(message "mouse-face: %s" prop))))
(define-key map "e" 'end-of-line)
(insert "before\n"
(propertize "TARGET\n"
'face '(:background "green")
'mouse-face '(:background "red")
'help-echo "click here"
'keymap map)
"*after\n"))
