As highlighted a couple of pages back here it's to comply with TfL requirements for 2024.
TfL seem to have moved from assuming passengers won't step out in traffic in front of a bus, to trying to make front of bus spread the impact and removing sharp bits like wipers from waist height (they have to be top hung). More pedestrian collision friendly.
If it actually makes any difference, or if emergency stops result in those standing being flung forward and hitting inside of windscreen instead remains to be seen.
