m_cachedImageSize already contains zoom-scaled dimensions when cached in
imageChanged(). Applying zoom again in calculateIntrinsicSize() caused
poster images to be incorrectly double-scaled.
Move poster size handling to calculateIntrinsicSize() to return the
cached size directly without additional scaling. Only apply zoom to
unscaled sizes from calculateIntrinsicSizeInternal().
