## Bug description

*Please describe.*  
When a user has a lot of distinct_ids, it could get ugly. 
*If this affects the front-end, screenshots would be of great help.*  
Viewing window at 33% and these are my distinct_ids

## Expected behavior
Should only show the first 3 distinct ids. If there are more than three, show a link that says "x distinct ids hidden. Click to show." When clicked, it should show all distinct ids.


## How to reproduce

1. Go look at profile for my email
2. 
3. 

## Environment

- PostHog cloud or self-managed?
- PostHog version/commit
