Defer not working in tests

Description

see this simple example to reproduce

// bug.gno
package bug

var number int = 0

func SetNumber(n int) {
	number = n
}

func GetNumber() int {
	return number
}

func reset() {
	number = 0
}

// bug_test.gno
package bug

import (
	"testing"
)

func TestSetNumber(t *testing.T) {
	defer reset()
	println(GetNumber())
	SetNumber(42)
	println(GetNumber())
}

Output:

=== RUN   TestSetNumber
0
42
panic: runtime error: index out of range [3] with length 1
