  \caption{\textbf{Analysis of over-propagation after object disappearance.}
    Over-propagation length is defined as the number of frames with non-empty prediction after the last frame where the ground-truth object is present.
    \textbf{(a)} Boxen plots (log-scaled $y$-axis) showing the distribution of over-propagation lengths for each model and prompting mode.
    \textbf{(b)} Stacked bar plots summarizing the severity distribution across four bins: perfect termination, minor, moderate, and severe.
    \textbf{(c)} Cumulative distribution functions of over-propagation length, with annotated 90th-percentile values ($P_{90}$).
