 You get no placeholder. And it plays, right? Because it's what it should
 do by default in a fresh Tor Browser 8.5.4 installation.

 Not so strange: you could be using a Tor Browser alpha and/or have
 installed a different NoScript version (not the one shipping with the
 browser). But you're standard, it seems.

 My answer is irrelevant, because even if I develop NoScript, I do not ship
 in the Tor Browser neither decide its configuration presets. On the other
 hand, you actually answering my question would have been helpful, as the
 security level determines what you can expect to be the "normal" behavior.

 However I've just tried to reproduce any anomaly on a fresh Tor Browser
 8.5.4 installation w/ default NoScript 11.0.2, both on Linux (Ubuntu
 18.0.4.3 LTS), macOS Mojave **and Windows 10**. I obtained the following
 expected behaviors for each of the three security levels, upon opening
 https://www.sample-
 videos.com/video123/mp4/720/big_buck_bunny_720p_10mb.mp4:

 1. STANDARD: the video plays as soon as the page loads
 2. SAFER: I get a window-sized placeholder, which if clicked opens a
 prompt to let me decide whether letting the video play. If I authorize it,
 the video plays as expected
 3. SAFEST: like #2 SAFER

 I cannot test on other platforms, but a Windows 7-specific bug of this
 kind would be extremely weird.

 Can you actually observe anything different?
 If you can, what is that?

 Thank you again.
