Scale a worksheet - automatic become 1

Description

I have an excel with Scale Height - Automatic. When I'm using GetMergeCells or something else that it's using f.workSheetReader(sheet), it breaks, Automatic become 1.

Steps to reproduce the issue:

package main

import (
        "fmt"
	"testing"

	"github.com/stretchr/testify/assert"
	"github.com/xuri/excelize/v2"
)

func TestLocalFile(t *testing.T) {
	xlsx, err := excelize.OpenFile("./test.xlsx")

	assert.Nil(t, err)

	mergedCells, err := xlsx.GetMergeCells("Sheet1")

	assert.Nil(t, err)

	fmt.Println(mergedCells)

	filenameXLSX := "./test_output.xlsx"

	xlsx.SaveAs(filenameXLSX)
}

excel:
test.xlsx

Describe the results you received:
go test

excel:
test_output.xlsx

Describe the results you expected:
It must remain Automatic

Output of go version:

1.16
