Inconsistent column ordering in the exported CSV file when valueField is numeric

[emaillenin]

Non-numeric example: (using 'A1' as valueField)

https://codepen.io/emaillenin/pen/ZEWKWrL

CSV Output:

"Date","A1"
"Monday","2025"
"Tuesday","2125"
"Wednesday","2225"

Numeric example: (using '1' as valueField)

https://codepen.io/emaillenin/pen/dyMWMJK

CSV Output:

"1","Date"
"2025","Monday"
"2125","Tuesday"
"2225","Wednesday"

Expected: Column order should be same as what is provided in the dataProvider
Actual: Column order changes based on the key.

I looked at the source code for the export function. I think this is happening because Amcharts is building an object with each valueField:value as a key:value pair. Ordering is done in this order:

1. integers in numeric order
2. strings in chronological order
3. Symbols in chronological order
