Chess (Fischer Random) (играпопереписке not supported)

[Vovadid]

Describe the bug
I use this script on my phone, open 2 windows, with the board and with your mod, and separate them across the screen. Everywhere the mod works but on Lichess in any mode it opens with an empty board and nothing happens, no hints appear.

To Reproduce
Steps to reproduce the behavior:

1. Download Firefox install the script on your phone
2. Go to the site Lichess and add it to your home screen
3. Go to the script and also add to your home screen
4. Launch 2 application windows split on screen
5. You can see that the script sees that the chess window is open, but the board itself is empty
