Formatting error: closing curly-brace placed to the last comment (using `visual` imports indent)

Valid code example (just from some crate documentation):

use binrw::{
    binrw,    // #[binrw] attribute
    BinRead,  // trait for reading
    BinWrite, // trait for writing
};

My rustfmt.toml:

imports_indent = "Visual"

Version of rustfmt: rustfmt 1.8.0-nightly (4392847410 2024-10-21)

Expected result of formatting example code above: (something like this, not sure)

use binrw::{binrw,    // #[binrw] attribute
            BinRead,  // trait for reading
            BinWrite, // trait for writing
           };

Actual result that breaks the code - closing curly-brace placed to the last comment:

use binrw::{binrw,    // #[binrw] attribute
            BinRead,  // trait for reading
            BinWrite  // trait for writing};

Start by reproducing the formatting of the documented Rust import with rustfmt 1.8.0-nightly and imports_indent = "Visual" in rustfmt.toml. Trace how line comments and the closing brace are handled, then ensure formatting keeps the brace outside the final comment and add coverage for this example.
