The DOM-widget width doesn't reliably track the node width in frontend 1.45, so force a fixed column count clipped the grid and the width floor blocked resizing down. Use flex-wrap (cells wrap to fit, never clip), drop the computeSize width floor (resize freely), and re-sync the widget width + reflow on manual resize.
