It sometimes happens with me that my wifi goes down in the middle of my work due to some issues (Usually gets fixed upon restart 
). In the classic editor, recovery was easily possible from such issues when you are connected to internet again. However, in the beta editor, it is not possible. Even if you get connected to internet again, it still shows all kinds of weird errors (Like Form is not defined). Finally, the only option left is to refresh the page and lose some of your work,
I understand that such issues will happen on the beta editor but please fix them as soon as possible.
