Artefacts on the table corners present when using dark streamlit themes

I noticed the AgGrid is rendered with small light artefacts on the 4 corners (see screenshot below):

This make it look out of place compared to the regular data table from streamlit. When using a Light streamlit theme, this is not noticeable.

I tested locally, but also on the demo app here: https://staggrid-examples.streamlit.app/
