Fixes the missing content in Jupyter Lab:

Who is a heavy Lab user that should review this?

This edit does allow the app viewer to expand, but I don't see content in it. I tested with Specviz and the content area remained blank even after I loaded a spectrum and some spectral lines. Things work as intended in a regular notebook, so there's still something strange going on with Lab.

I had some Lab issues but was able to resolve them by starting from a clean conda environment and reinstalling everything there. Once I did that I was able to confirm that the app displays properly in Lab, as seen below. Approving.

Hmm... Would be nice if @ojustino can also confirm that it works in a clean environment.

[pllim]

@rosteen , just to be sure, does it still work when you pop it out?

[rosteen]

@pllim I'm a total Lab noob, you're going to need to define what you mean by "pop it out".

[ojustino]

@rosteen Good call on starting from a clean conda environment. I did that and got the intended results.

Perhaps @pllim was talking about right-clicking the cell containing the app and selecting "Create New View for Output" like we discussed around the time of the JWebbinar? If so, that works for me.

Create New View for Output

Exactly. Ricky and I resolved that "offline." 😸

Thanks, everyone!
