Thanks for flagging that @Charly_Wargnier, I’ll take a look
Somehow didn’t spot there was already a reply here so sorry if this is duplicating work.
I put up an issue and small PR https://github.com/streamlit/streamlit/issues/1441
No problem at all @Ian_Calvert, thanks for doing that! I’ll try and review your PR today
