>>>   My Info:   Win7_64, Nightly 49, 32bit, ID 20160526082509
STR_1:
0. Set Flash to "Ask to activate" or intall an obsolete version of Flash
1. Open  http://tvzvezda.ru/news/sport/content/201606111555-edp6.htm  in a new selected tab
2. Wait 1 minute (or maybe less. See screencast)

STR_2:
0. Set Flash to "Ask to activate" or intall an obsolete version of Flash
1. Open attached "testcase 1"


AR:  Plugin notification appears and disappears, so content on the page twitches
ER:  Either X or Y  (i.e. please leave content along)
 X) No Flash plugin notification at all
 Y) Flash plugin notificaion shouldn't disappear

Note:
 Marked as regression, because at some point (bug932854) content started to twitch w/o clear reason

This is regression from bug 932854 (see Note 2). Regression range:
