I've put valuelist checkboxes on brand new layout. I tried to make the object frame as small as possible, to just let the actual checkbox frame visible.
But if I toggle the checkbox object lines to none rather than solid 0, the checkbox frame visible isn't visible entirely anymore : object lines set to none take more estate than lines set to solid with 0 thickness. That's really weird, it should be the same or at least the opposite.
Here are screenshots
And that bad behavior still shows in browse mode.
Furthermore the solid way could take more CSS space than none, so that's more cluttered CSS
