Running format twice produces different output

[giordano]

Reproducer using JuliaFormatter v1.0.62:

julia> using JuliaFormatter

julia> text = "push!(attributes, operandsegmentsizes([1, 1, 1, (lhs_scale==nothing) ? 0 : 1(rhs_scale==nothing) ? 0 : 1]))";

julia> style = BlueStyle();

julia> println(format_text(text; style))
push!(
    attributes,
    operandsegmentsizes([
        1, 1, 1, if (lhs_scale == nothing)
            0
        elseif 1(rhs_scale == nothing)
            0
        else
            1
        end
    ]),
)

julia> println(format_text(format_text(text; style); style))
push!(attributes, operandsegmentsizes([
    1,
    1,
    1,
    if (lhs_scale == nothing)
        0
    elseif 1(rhs_scale == nothing)
        0
    else
        1
    end,
]))

I have noticed this as well. I've found that in most cases, running it 3 times produces an output which does not change.
