Change auto selection behaviour of emoji and slash commands to be more UX/Type friendly

## What does this MR do?
In the context of a special command (starting with "/", ":", ...), the MR disables auto selection of first item in the dropdown suggestion menu, until at least a character has been typed.
This behavior change originated from #22058 and #23578 in which problems with the ":" special command were pointed out.

## Are there points in the code the reviewer needs to double check?
At lines +187 and +242 there were originally no sorters. Given what ``DefaultOptions.sorter`` does, I don't think it is a problem.

## Why was this MR needed?
To solve #22058 and #23578

Remove an extra leading space from diff paste data

## What does this MR do?

Remove an extra leading space from diff paste data.

## Are there points in the code the reviewer needs to double check?

I have checked the following three patterns.

* inline diff
* parallel diff
* blob preview

## Why was this MR needed?

Diff paste data contain an extra leading space.
So it need to remove an extra leading space manually from pasted diff data.
