Tabulator checkbox truncated in panel_material_ui

Hi,
After installing and importing ‘panel_material_ui’ into my application, I noticed a minor issue with the tabulator widget in ‘checkbox’ selection mode. The checkbox in the table header that is used to select all rows is truncated. See the screenshot below.

Does anyone know how to fix this small but annoying issue?

Thanks, Stefano

Can you file an issue in panel?
