Feat: Jump back to message after jumping to reply

### Your use case

#### What would you like to do?

When jumping to a reply, often I will wanna go back to the message that I was previously at, where I got the reply from.

#### Why would you like to do it?

Usually I check a reply to get context, and as such doing this serves the purpose of getting context without having to scroll back to a specific conversation manually. Often, the message with the reply is not from an ongoing conversation

#### How would you like to achieve it?

After hitting a reply, I would like to either have a separate button, or have the "jump to bottom" button act as a button to jump to the message I got the reply from.

### Have you considered any alternatives?

Scrolling is tideous, especially when it is a long chain of replies.

### Additional context

Preferably, this would stack so that even when you hit multiple replies, you could backtrack until eventually you came back to the first reply you clicked.

### Are you willing to provide a PR?

No

The issue names no files, tests, or entry points. First clarify whether the navigation should use a separate backtracking control or repurpose the jump-to-bottom button, then define stacked reply navigation and its completion criteria before locating the relevant Android message-navigation flow.
