Changing the Object prototype breaks $.isEmptyObject

[ljharb@…]

If you change the Object prototype, $.isEmptyObject({}) will return false - and it should always return true for an empty object literal.

This is fixed in ​https://github.com/jquery/jquery/pull/179

I can only restate what scott.gonzal already said 3 years ago

Modifying Object.prototype is an extremely bad practice. jQuery is not supported on any page where this occurs.

But you can follow the ticket mentioned below for progress on this issue.
