Suggestion of improvement when embedding content for better user experience

[moodlemobile]

In order to provide a better experience to users when embedding content from the site (for example, a Moodle site page with a code to embed a video) we recommend using our component "core-iframe" instead of just iframe as it will automatically log in the user into the site (Android and iOS)

Our suggestion will be to update this line:
https://github.com/streamingltd/MEDIAL-Moodle-Activity/blob/603f7c1374cefa3826c26e943f5ac0de85f07af7/templates/mobile_view_page.mustache#L5

With something similar to was used here:

This seems like a useful change, which I've just tried on our test system. I'm guessing that there are some css diffferences in Moodle mobile that affects how core-iframe adapts to the screen size, since it caused the frame to constantly jump back and forth between two sizes making the video unuseable. (See attached video).

I experiencend the same problem on two different Android devices with the latest MoodleMobile. Reverting to a regular Iframe fixed the problem.

I tried taking out all the attributes from core-iframe leaving just:

<core-iframe src="{{launchurl}}" ></core-iframe>

In case the height or style that is there was causing the issue, but it made no difference, the resizing just continued in a loop.

It may be there is something in the MEDIAL code within the Iframe I can do to mitigate this, but any thoughts on the cause here would be appreciated.
