Tileview Borders

I have a tile view with tiles at 0,0 and 0,1. I want to set the border for it when it’s “scrollable”. What I see is that 0,0 has left and top border and 0,1 has left border only. I’m suspecting that this is because it’s some sort of grid, and 0,0 is top left (thus left and top borders are set).

Do you know how to just set the border on the tileview in view? Alternatively, do you know if tile view has some default grid size that is different from the loaded tiles?

self.tileview.set_style_border_color(lv.color_white(), lv.PART.MAIN)
self.tileview.set_style_border_width(2, lv.PART.MAIN)
self.tileview.set_style_border_side(lv.BORDER_SIDE.FULL, lv.PART.MAIN)
