This issue affects YouTube videos as well. They still display the
"fullscreen" icon, but clicking on it doesn't go to full screen. Instead
it displays a message: "Full screen is not available. Find out more"

Bug description:
I've found a lengthy discussion concerning the disappearance of the
fullscreen button on Vimeo forums, where many people are complaining
that is stopped working recently on various platforms:
https://vimeo.com/forums/help/topic:277610
https://vimeo.com/forums/help/topic:277610#comment_13981805
So here is a response from Vimeo from another forum.
1. In the past, fallback options in the browser allowed some version of
fullscreen to operate even when within frames.
2. Within the last few weeks, updates to major browsers removed these
fallback options. This caused the fullscreen button to fail when clicked. Vimeo
videos would no longer enter fullscreen if they were placed within frames.
3. Because the button wouldn’t work anyway, in the last few days our
developers have now removed the fullscreen button from any players that are
embedded within frames. To confirm, the button would have been broken even if
displayed. So, whether the button was there or not, your viewers would not be
able to enter fullscreen.
The recommendation from Vimeo support is the following:
https://vimeo.com/forums/help/topic:277610
If your embedded video is missing the fullscreen button in the Player, your
embed code is likely missing these three required fullscreen attributes:
webkitallowfullscreen mozallowfullscreen allowfullscreen
Our embed code includes these attributes by default, but if you have modified
the embed code, or used another service to generate the embed code, it's
possible these attributes are missing. An example of how the Vimeo embed code
should appear is shown in the code block below.
NOTE: If the Vimeo iframe embed code is placed within another iframe, that
parent iframe must also include the same fullscreen attributes.
Once these fullscreen attributes are included, the Player will display the
fullscreen button again.
<iframe src= "https://player.vimeo.com/video/137003356"; width="500"
height="281" frameborder="0" webkitallowfullscreen mozallowfullscreen
allowfullscreen></iframe>
The recommended code is exactly what we are using, but fullscreen does
not work in Mahara, while it works in Moodle (in the same browsers).
Mahara seems to be stripping the necessary attributes
webkitallowfullscreen mozallowfullscreen allowfullscreen on page view,
while they are in the embed code when I confugure the External media
block.
You can see an example in Mahara here https://mahara.org/user/lenkak/page-1
-- no fullscreen button
Fullscreen working in Moodle here https://lenka.moodlecloud.com/ (you need to
log in as guest)
In this example video the lack of the fullscreen button is not such a
problem, because there is a link to Vimeo where you can watch the
video in fullscreen, but our clients are using private videos
restricted to the Mahara domain, so that can be played only when
embedded in Mahara, not on Vimeo.
I have tested Mahara 1.10.8, 15.10.2testing and mahara.org -- same
problem.
