Panel appears to have a hard time rendering and removing GIF panes when the supplied GIF file is "large" (the file sizes that I have been using are ~200KB). Specifically for the plot loading indicator (labeled obj_loading), this has led to instances where the GIF either doesn't properly load in time or won't be removed from view after being replaced with a Plotly plot in the code.
So far, this appears to only be a problem when serving the application on linux platforms. Additionally, the problem seems to go away when we turn on automatic threading with either the --num-threads=... option of panel serve or the nthreads=... argument of pn.extension() ; however, this then sometimes bug out the non-throttled sliders.
A possible solution for this would be to not use GIFs for custom indicators at all and just resort to Panel's (significantly more boring) pn.indicators objects.
