Bug description

The avatars shown at the top of various pickers seem to be slightly lower than they should be. For example, in the viewer picker for private stories, in the picker for adding people to groups, etc.

Steps to reproduce

1. Create a private story or edit an existing one > tap "Add Viewers".
2. Select one or more users to add to the story.

Or:

1. Go to the chat info / settings of a group.
2. Press "Add Members".
3. Select one or more users to add to the group.

Actual result: The avatars shown at the top are not vertically aligned with the background.

Expected result: The avatars shown at the top should be vertically aligned with the background.

Reproduce the issue in the private-story viewer picker and the group Add Members picker on iOS, using the steps and screenshot in the report. Inspect the picker UI implementation and compare the selected avatars with their background; done means the avatars are vertically aligned in both picker flows.
