Context menu icon not displayed the first time about ipydatagrid

[martinRenou]

Do you have an idea what could be the origin of this issue @kaiayoung ?

[martinRenou]

Can you reproduce it locally? I always have it the first time I display a grid on the page, the second time is fine

Thanks for reporting this! I haven't observed this yet, but it does look like font-awesome had not loaded yet. I had just relied on it being available from ipywidgets, but we may want to import it on the ipydatagrid frontend as well, to ensure that it is always available when needed.

I did try to import font-awesome but it does not fix the issue..

[kaiayoung]

I'm tempted to just manually draw an icon in the canvas with a path, and just avoid font-awesome completely... I think the config parameter has the height/width, etc for the renderer, so it may not be too bad?

I guess it would be fine drawing it indeed.
