Description Kirill S. Dmitrenko 2017-09-28 07:10:36 PDT 
1. Open https://yandex.com/maps/213/moscow/?ncrnd=3459&ll=37.583335%2C55.733222&z=16&l=stv%2Csta&panorama%5Bpoint%5D=37.588440%2C55.733808&panorama%5Bdirection%5D=171.429911%2C-4.006784&panorama%5Bspan%5D=120.000000%2C75.351069
2. Drag panoramic image
3. Swtich tab
4. Return to the tab with Yandex.Maps
5. Player is black

That's a regression that was introduced in Safari 11 (same problem in TP). I wasn't able to isolate smaller test case:( Is there a way to debug this with internal WebKit tools?

I cannot reproduce this with macOS High Sierra on a 15" Mid 2015 MacBook Pro.

What hardware and OS are you using? Can you try other configurations to further isolate the problem?
Comment 2 Jon Lee 2017-09-28 10:06:05 PDT 
I could reproduce on iMac. As soon as I drag again the panorama returns.

Any news?
Comment 6 Jon Lee 2017-10-25 10:02:05 PDT 
Not yet, but it's in our queue.
Comment 7 Dean Jackson 2018-01-29 13:31:16 PST 
I can no longer reproduce this on a MacBook Pro or Mac Pro running the seed of 10.13.4, using Safari Technology Preview 48.

Kirill, can you try again with an updated configuration?
Comment 8 Kirill S. Dmitrenko 2018-01-31 05:07:11 PST 
We can't reproduce the problem on available configurations too (Safari 11.0.3 on 10.11.6, 10.12.6 and 10.13.3). And there're no more user complaints about it to our support.
