No preventing mouse events when disconnected from the livebook server

[cocoa-xu]

Currently, when the frontend is disconnected (could be OOM/a crash/no Internet) from the livebook server, the phx-loading css class will prevent mouse events like scrolling and selecting.

From my own view, it feels nicer if it’s possible to remove that so that the user can copy the unsaved code when a crash happens (or whatever causes the disconnection).

I know that the shortest autosave time is 5 seconds, but sometimes I forget what I’ve typed in the last five seconds, esp. when copying and modifying a function to match a sub-case. It would be good if it allows the user to scroll up/down and check what didn’t get saved (and copy that to the newly opened session).

WDYT?

Hey @cocoa-xu! Sounds like a good call to me, especially that Phoenix no longer does it in newly generated apps. I'll change it :)
