Fix Caption preview SubtitleView textSize cannot update correctly

Browse Source 
Root caue: When received #OnLayoutChangeListener callback, the mPainText size keeps "zero" after called setTextSize() because the requestLayout() does not trigger the whole view re-measure & re-layout in not ui thread.
Solution: Post #refreshPreviewText to ui thread to get correct bounds to
measure & layout.
