New line in richText cell

Take the following code:

let excel = require('exceljs')
let wb = new excel.Workbook()
let ws = wb.addWorksheet('test')

ws.getCell('B2').value = {
  richText: [
    {
      font: {
        color: {
          argb: `99E391`
        }
      },
      text: `Chuck Norris' tears cure cancer,\n`
    },
    {
      font: {
        color: {
          argb: `FF6565`
        }
      },
      text: `too bad Chuck Norris has never cries.`
    }
  ]
}

wb.xlsx.writeFile('./test.xlsx').then(err => {
  if (!err) {
    console.log(`file written successfully.`)
  } else {
    console.log(`error writing file: ${err}`)
  }
})

The result will be a string resembling the following (Ignoring the line break):

Chuck Norris’ tears cure cancer,too bad Chuck Norris never cries.

It seems as though the line break is being stripped from the ends of the text property when the file is being written.

By simply adding a character after the \n the line break does not get removed. Is there a setting somewhere to turn this functionality on or off?

It works for me, if I change the code in the 3 modules

node_modules\exceljs\dist\es5\xlsx\xform\strings\text-xform.js
node_modules\exceljs\dist\exceljs.js
node_modules\exceljs\dist\exceljs.min.js

from:

if (model[0] === ' ' || model[model.length - 1] === ' ') {
      xmlStream.addAttribute('xml:space', 'preserve');
 }
``

into:

if (model[0] === ’ ’ || model[0] === ‘\n’ || model[model.length - 1] === ’ ’ || model[model.length - 1] === ‘\n’) { xmlStream.addAttribute(‘xml:space’, ‘preserve’); }
