🐛 Revert blend-mode hover preview when dismissing dropdown (#9237)

* 🐛 Revert blend-mode hover preview when dismissing dropdown

When the blend-mode dropdown was dismissed by clicking outside instead
of selecting an option, the canvas kept rendering the last hovered
blend mode even though the inspector and data state had reverted. The
visible state of the shape no longer matched its stored state. Reset
the canvas render back to the shape's saved blend mode on dropdown
close so the preview never outlives the dropdown.
