STR_1:
1. Open url any "bad" url - [1],[2],[3] or any "good" url - [4],[5],[6],[7]
2. Hover mouse over the video
3. Move mouse away from the video

bad
> [1] data:text/html,<video muted="muted" controls="" id="V" autoplay="autoplay" ></video>
> [2] data:text/html,<video muted="muted" controls="" id="V" ></video><script>V.play()</script>
> [3] data:text/html,<video muted="muted" controls="" id="V" ></video><script>setTimeout("V.play()",100);</script> 
 
good
> [4] data:text/html,<video muted="muted" controls="" id="V" ></video>
> [5] data:text/html,<video muted="muted" controls="" id="V" autoplay="autoplay" ></video><script>V.play()</script>
> [6] data:text/html,<video muted="muted" controls="" id="V" src="https://videos.cdn.mozilla.net/uploads/mozillaorg/A%20different%20kind%20of%20browser.webm"></video>
> [7] data:text/html,<video muted="muted" controls="" id="V" autoplay="autoplay" src="https://videos.cdn.mozilla.net/uploads/mozillaorg/A%20different%20kind%20of%20browser.webm"></video>



Actual Result:  ("-" and "+" only represent the presence of video controls)

 Url      Controls after Step 1       Controls after Step 2        Controls after Step 3
 
 [1]           (-) hidden                (+) visible                  (+) visible
 [2]           (-) hidden                (-) hidden                   (-) hidden
 [3]           (+) visible               (+) visible                  (+) visible
 [4]           (+) visible               (+) visible                  (+) visible
 [5]           (-) hidden                (+) visible                  (-) hidden
 [6]           (+) visible               (+) visible                  (+) visible
 [7]           (-) hidden                (+) visible                  (-) hidden



Expected Result:  Either X or Y
 X) Step 1 - controls should be visible  Step 2 - should stay visible   Step 3 - should be visible
 Y) Step 1 - controls should be hidden   Step 2 - should be visible     Step 3 - should be hidden
Explanation:
 Video controls should only depend on the video state and current mouse position.
 If video is in "play"/"paused" state, it should only display controls if mouse is placed above video
 If video is in "not started"/"invalid" state, it should always display controls
 This looks like current plan of Firefox team
 In each case video should have unequivocally certain "state", and therefore - behavior of controls
 In other words, in each "bad" and "good" case I expect either X or Y
 


Note:
 I encountered this on a number of sites using normal PC, and also almost everywhere
 while using PC w/o native video decoding.
