Chrome Version: 68.0.3433.0
OS: Linux

What steps will reproduce the problem?
(1) Launch a video in PiP from one tab
(2) Open a second tab, launch a video in PiP through it (replacing first one)
(3) Close second tab
(4) Attempt to relaunch the video from the first tab in PiP again

The expected result is to see the video from the first tab show up in PiP, starting off from where it paused when the second one was initially launched.

Instead, Chrome crashes.
