The mixin was caching canvas width/height in mounted() hook, which caused drag boundaries to become incorrect when the canvas size changed due to zoom operations (scale property changes). This fix replaces the cached pageWidth/pageHeight with a getCurrentPageDimensions() method that queries the canvas dimensions on-demand, ensuring elements can move within the correct boundaries regardless of zoom level. Fixes draggable element boundaries when PDF zoom changes. Signed-off-by: Vitor Mattos <1079143+vitormattos@users.noreply.github.com>
