macOS' windowing system handles picture-in-picture differently from other windows, as can be observed when using PIP in Safari or other apps that implement PIPViewController, such as IINA. Chrome instead implements its own PIP windowing. macOS windowing tools, such as Mission Control, interfere with Chrome's PIP windows. This provides an inconsistent experience for users who watch video in different apps on Mac.

Notice how Chrome's PIP window differs from Safari's:
- On activating PIP, there is no transitional animation
- The PIP window doesn't bounce from the edge of the screen, but instead gets stuck in a partially hidden place
- You cannot move the PIP window to the edge of the screen and temporarily "hide" it. PIPViewController honours this, blurs the window, and shows a chevron.
- The PIP window is tied to a Space in macOS windowing. Thus, it doesn't stay on screen when entering fullscreen in Chrome.
- Dragging the PIP window is buggy
- Mission Control shows the PIP video as a separate window, even though it is conceptually an extension of the page in Chrome.

Able to reproduce the issue on mac 10.13.3, win-10 and ubuntu 17.10 using latest canary #69.0.3446.0.
There are different behaviour for different OS:
For OS-Mac:
===========
- On activating PIP, there is no transitional animation
- The PIP window doesn't bounce from the edge of the screen, but instead gets stuck in a partially hidden place
- You cannot move the PIP window to the edge of the screen and temporarily "hide" it. PIPViewController honours this, blurs the window, and shows a chevron.
- The PIP window is tied to a Space in macOS windowing. Thus, it doesn't stay on screen when entering fullscreen in Chrome.
- Dragging the PIP window is buggy
- Mission Control shows the PIP video as a separate window, even though it is conceptually an extension of the page in Chrome. 
For OS-Win:
===========
- The PIP window when resized blinks and get stuck and doesn't play properly.
For OS-Linux:
=============
- The PIP window when resized, the browser hang and crashes.

Note: This only works in Chrome 68 or later. Hence, marking it as untriaged to get more inputs from dev team.

Thanks...!!

Routing to PIP owner for further triage.

Is there any update on this? With the recent release I expected this to be using macOS' native functionality. Currently having to decide between using Spaces or PIP due to this.
