it seems this is caused by Avm2ButtonData.hit_area having its parent set in Avm2ButtonData::create_state then not removed until you mouse over the misplaced hitbox. (note that hit_area itself is set after calling create_state in <Avm2Button as TDisplayObject>::construct_frame)

this causes incoming mouse events to get transformed twice; once because it's assumed hit_area has no parent in <Avm2Button as TInteractiveObject>::mouse_pick so the mouse event is transformed to local space and again through TDisplayObject::hit_test_shape.

this is fixed in #8744
