Steps to Reproduce

async def callback(update, context):
  # current_user_id = update.effective_user.id
  # other_user_id = httpx.get("network/call")
  # this is updated in persistence
  context.user_data['key'] = value
  # this is not updated in persistence
  context.application.user_data[other_user_id]['key'] = 'value'

Expected behaviour

user_data corresponding to other_user_id should be updated in persistence

Actual behaviour

only user_data corresponding to current_user_id is updated in persistence
