Subject: elm_panel: add exception handling in _drawer_close()
X-Git-Tag: submit/tizen_4.0/20180124.101838~6
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=70ae00f8821c7ea007aeabb04b1beb3bf95cd65c;p=platform%2Fupstream%2Felementary.git

elm_panel: add exception handling in _drawer_close()

this fixes a bug with scrollable panel not being blocked
when it is closed. scroll is blocked in _anim_stop_cb(),
which is called after elm_interface_scrollable_region_bring_in().
but if panel content is already at the target position, _anim_stop_cb()
is not called. so there is a need to check content's position and
handle the exceptional case.
