Very long use line fails to format

[conradludgate]

Reproduction:

use a::very::very::very::very::very::very::very::{

    very::very::very::very::very::very::very::very::very::long::Path
};

This tries to format into

use a::very::very::very::very::very::very::very::very::very::very::very::very::very::very::very::very::long::Path

Which I think triggers some misbehaviour and causes the block of imports to fail to format silently.

If given another item in the long module chain, it can format fine:

use a::very::very::very::very::very::very::very::{

    very::very::very::very::very::very::very::very::very::long::Path,
    another::path,
};
// turns into
use a::very::very::very::very::very::very::very::{
    another::path, very::very::very::very::very::very::very::very::very::long::Path,
};

Amount of modules doesn't change anything, only the number of characters.

After experimenting a bit, there might be other parameters at play, like byte length and module nesting possibly ?

use ඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞ::{

    ඞ::ඞ
};
// one more ඞ
use ඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞ::{

    ඞ::ඞ
};
// less nesting but longer
use ඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞ::{

    ඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞ
};

only formats the second one incorrectly:

use ඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞ::ඞ::ඞ;
// one more ඞ
use ඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞ::{

    ඞ::ඞ
};
// less nesting but longer
use ඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞ::ඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞඞ;
