Nobody here has faced to this bug? Just start a new ethercalc, pin it, edit cells and then detach widget. I don't see the edited cells

It looks like the room ID for the embedded widget gets encoded as https://ethercalc.net/!roomId%3Amatrix.org, which is treated as a separate URL from https://ethercalc.net/!roomId:matrix.org displayed in the widget info.

As a workaround for the moment, you could use the %3A form in the separate tab.
