Bug: Eye Dropper Randomly Edits Variables

Sometimes the color picker/eyedropper stops working on the selected object.
Steps: Select a rectangle → click its fill color → use the eyedropper to pick a new color.
Expected: The rectangle’s fill changes to the picked color.
Actual: Instead, an existing color variable (in the Variables table) gets updated with the picked color, as if that variable was selected. I didn’t open the Variables panel or select any variable.
