Due to a bug, for each TTML node, when applying its style to the encompassed regions, it applies child nodes's styling several time for each region (the number of time is equal to the number of region). This leads to a styling issue if there are multiple regions in a node displayed at the same time in TTML file. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=196810046
