Empirically, our analysis reveals that this stems from \\textbf{visual dominance}, where the reference image causes severe attention dispersion, inhibiting the model's ability to incorporate new semantic information. To address this, we propose \\textbf{AlignVid}, a training-free intervention that re-calibrates the model's internal attention distribution.
