Send Request Button Turns Dark Grey

[mattbaseball]

Describe the bug
There is a bug which turns the send friend request button to a dark grey. Can not yet identify why only some change colour and why it is only them. This has also happened on both devices I have tested with (Galaxy S9 and Galaxy A71, both on API 29). Lastly, the button seems to still be fully functioning, even though the colour has changed.

To Reproduce
Steps to reproduce the behavior:

1. Go into add friends
2. Type random letters as if you were to search.
3. Delete a few letters
4. Observe some of them may have changed colour.

Expected behavior
To maintain the same colour.

I've also discovered that your account needs to have one or more friends for this glitch to occur. In addition, it seems like the majority of the accounts that have the dark button have a pending friend request. This is not all of the time though and is likely just due to a strange chance.
