Bug description

You can open RecipientPreferenceActivity twice (on top of each other)

Steps to reproduce

• open a conversation
• rapidly tap the contact name
• watch the contact name animation happen twice and RecipientPreferenceActivity open (twice)
• tap the back arrow on top left

Actual result: RecipientPreferenceActivity is still open
Expected result: You get back to the conversation

Also happens on 3.24.1

Confirmed by Twitchy Fingers himself 😉
With 3.26.2

Also notice, that the contact name vanishes if both RecipientPreferenceActivity get closed

Same for me on 3.27.0 on a Pixel 7.1.1.

This happens in a lot of places. For example, go into Signal's notification settings and hit "Sound" twice rapidly. The sound selector will show up twice.

Still a reproducible issue. (4.42)

When I try to reproduce this in 4.42.3 what I do is hammer about six taps in rapid succession onto the name of the contact in the titlebar of my 1-on-1 chat... as described above, I see two transition-animations of their avatar-pic opening up the activity twice. However, after hitting the back-button a couple of times to return to the chat-history of the 1-on-1, sometimes -- not sure if it is always? --

the small circular avatar-picture in the titlebar is gone... there is a blank area with the background-color of the titlebar where the tiny-circular-avatar-pic used to be... as if hammering on it made it disappear :-) It stays gone, until you back up to the conversation-list, and then re-open the conversation-list item in question, as which point the titlebar once again has the avatar-pic in it as expected.
