The invert_checkbox parameter was not working if used along an icon (override in python or not)
Exemple code:
props = context.scene.eevee col.prop(props, "use_taa_reprojection") #default for reference col.prop(props, "use_taa_reprojection", icon='NONE', invert_checkbox=True) #work col.prop(props, "use_taa_reprojection", icon='RENDER_STILL', invert_checkbox=True) #don't work
