ISSUE
Video links in chat, such as Youtube, Streamable, or even messages recieved from friends using the Chat's built in image/video uploading feature, no longer display in my Chat client.
It displays the icons that seem to appear when the "Don't embed media in-line" option is checked, but I don't have it enabled. Images are random as to whether they'll be visible or not, links will almost always show their preview properly.

OS
Windows 10, latest Beta client.
Also tested with a full fresh install, still occurred.

STEPS
Paste Youtube Link.
Video will not embed.

EXPECTED
Video visible in chat, fully playable.
