insertText() with format value of empty string changes the dates to show as numbers

[tdclaritum]

If $excel->insertText() is called with format param set to empty string it will change the formatting of the date columns and they are displayed as numbers. It doesn't matter if $excel->insertDate() will insert the date to the same column or different. The date always shows as a number

Code to reproduce

<?php
require_once "vendor/autoload.php";

$excel = new \Vtiful\Kernel\Excel(['path' => __DIR__ . '/data/cache/']);

$dateFile = $excel->fileName("free.xlsx")
    ->header(['date']);

$excel->insertText(1, 0, "1", '');
$dateFile->insertDate(2, 0, time(), 'yyyy-mm-dd hh:mm:ss');


$dateFile->output();

Expected result

date
1
2024-09-19 10:34:47

Actual Result

date
1
45554.43352
