If you make a request with the following parameters,
webix.ajax("data.php", {
"some&key":"some&Value"
});
only values will be escaped, not the fields. It can lead to errors.
Request URL: https://snippet.webixcode.com/data.php?some&key=some%26Value

P.S:
The documentation on https://docs.webix.com/api__refs__ajax.html is not correct.
“webix.ajax.post” not work.
