Fullscreen on close is not disabled

[lucianobosco]

Fullscreen is not disabled on modal close.

"vue-cool-lightbox": "^2.7.4",

Steps to reproduce:

1. Use the fullscreen sample
2. Click the fullscreen button at the top right. Browser will go to fullscreen mode
3. Click on the close button "X" at the top right.

Expected behavior: lightbox should be closed and also browser should return to normal mode
Current behavior: lightbox is closed but the browser keeps in fullscreen mode. The only way to disable it is by pressing F11

Please note that by pressing Esc when in fullscreen mode, instead of closing the modal, it goes back to normal mode.
