Just upgraded to 7.7.1

When a user tries to post a video (See Photo1) They paste the youtube link in the box and then post their topic ... the page creates blank space where the video should be but the video never shows. (see photo2)

If I replace the code (by using chromes edit html functions) with the embedded code from youtube (which is iframe instead of embed) it works fine. See photo3

The original code that does not work is (see photo2)

Code
<embed src="http://www.youtube.com/v/tSx2OSuEzDI" type="application/x-shockwave-flash" wmode="transparent" width="425" height="350">

The youtube code that works (see photo3)

Code
<iframe width="560" height="315" src="https://www.youtube.com/embed/tSx2OSuEzDI" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>

Anyone else having this issue?
