Disappearing chromospyce output cells

[dvdkouril]

Not sure about the exact conditions, but often the chromospyce widget disappears from the output cell after a while.

Example:

Screen.Recording.2024-12-18.at.9.28.10.AM.mov

Here I run the cell that displays a chromospyce widget, then scroll down the notebook. When I scroll back up, the cell output is gone.

Possible causes:

• Maybe it has to do with the DOM: since the canvas gets out of the view, it's removed from the DOM and then I don't do something I should to redraw the cell output
  • I wonder if the same happens also with the option alwaysRedraw: true sent to the chromospace.display() function.
