Bug Report:

⚬ BUG:
Unable to get to the default settings after close "forced theater mode"
⚬ HOW:
The original screen size is on the upper left side. I turned on forced theater mode and soon saw the player screen become bigger, takes the whole screen, and then turned it of but the screen size didn't go back. Even tried uninstall the extension and still didn't work.
⚬ EXPECTED (/preferred) behavior:
After close this mode, the player size will go back to youtube default size.
⚬ Screenshots:

@WhiteMasky Hi, I worked over the issue, and fixed it.I am attaching a video URL Working Video Drive Link.
I did changes in js&css/web-accessible/www.youtube.com/appearance.js

Original Code

Changes from my side

I don't know what cookie to be set when theater mode is off.
Improvement suggesting are welcomed.
