Line comments turned into block comments despite `normalize_comments`

[micouy]

Input & expected output

fn main() {
    match a {
        b => c,
        // b => c,
        // b => c,
    }
}

Output

fn main() {
    match a {
        b => c,
        /* b => c,
         * b => c, */
    }
}

Config

imports_layout = "HorizontalVertical"
max_width = 80
normalize_comments = true
match_arm_blocks = false
wrap_comments = true
blank_lines_upper_bound = 2
merge_imports = true
report_fixme = "Always"
report_todo = "Always"
use_field_init_shorthand = true
reorder_impl_items = true

Unfortunately I can't reproduce it in the playground.

EDIT: changed the example code

• rustfmt version: rustfmt 1.4.21-nightly (01f2eadc 2020-09-04)
• From where did you install rustfmt?: rustup

Seems to only happen within a match and with normalize_comments enabled
