Why this change is needed?
This custom formatting commonly shows up in exported timesheet data from a large company.
When the escaped space isn't kept it will lead this to the format array being exploded into 3 pieces. Then at https://github.com/PHPOffice/PhpSpreadsheet/blob/1.3.1/src/PhpSpreadsheet/Style/NumberFormat.php#L468 the check only only take the firs block which is 'hh:mm:ss' so it assumes 24 hour but then later in the loop you'll have 'am/pm' which gets converted into A. When all is said and done you can get AM/PM on a 24 hour value.
