Incorrect output with -R flag

[palage4a]

I get strange output if i run tests with -R flag and one of the tests fails. See repro.

Repro
Install luatest:

tt rocks install luatest

Version:

$ cat .rocks/share/tarantool/luatest/VERSION.lua
return '1.0.1'

Create a test:

local t = require('luatest')

local g = t.group()

local max_count = 5
local counter = 0

g.test_repro = function()
    counter = counter + 1
    t.assert_lt(counter, max_count)
end

Output:

$ .rocks/bin/luatest ./test/repro_test.lua -R 5
Tarantool version is 3.1.0-0-g663f509a2
....F
