@magiconair could you please take a look? Thank you

[magiconair]

I'll have a look over the weekend. Want to make sure that the right tests are covered.

It was a year since the last response. Any progress in reviewing so far?
Thank you

[magiconair]

This looks good to me. Will this break any existing code or break reading existing files?

[magiconair]

Sorry for the late response

[apesternikov]

This change would not break reading existing files since it only affects writing.
Speaking of breaking existing code - it is entirely possible that code relying on this bug presence exists. I am not specifically aware of such code. According to https://pkg.go.dev/github.com/magiconair/properties?tab=importedby 223 opensource projects imports this package as of today, I am not sure how many of them are using the writing path.
If you want to make sure no existing code is affected you can probably consider releasing v2?

[apesternikov]

ping?

[magiconair]

Lets do this.

[apesternikov]

thank you!
