How to hide lines generated with calls from IPython's publish_display_data function?

[maximlt]

Hi all,

I'm one of the maintainers of the plotting library hvPlot. The library depends on the dashboarding library Panel to handle layouts and to enable interactive plot exploration. When hvPlot is imported, Panel injects some JS and styling into the notebook using IPython's publish_display_data function, calling it three times. This is required to enable some interactivity. Doing so in a VSCode notebook displays three empty rows. Is there a way to hide these empty lines?

In Jupyterlab, this only displays a small empty line (which is a bit less annoying):

For reference: holoviz/hvplot#1284
