Issue description or question

Sample code

// paste the code you are running here
import slide_out from 'devextreme/ui/slide_out';

const existingParamList = [1,2,3];
const mnemonic=5;
const updatedParam = [...existingParamList, mnemonic];
console.log(updatedParam);
console.log(updatedParam.join(','));

function getSplit(b) {
    return b && b.toString() && [b].join(',').split(',') || [];
}

let a = undefined;

a = [1,2,3];
console.log('xxx', getSplit(a))

a = '1,2,3';
console.log('xxx', getSplit(a))

a = '';
console.log('xxx', getSplit(a))

a = [];
console.log('xxx', getSplit(a))

console.log('xxx', getSplit(undefined))
console.log('xxx', getSplit(null))

console.log('array is', [].toString() ? 'not empty' : 'empty');

console.log('empty array length is', [].join(',').length);

Sample repository link

If the issue can not be reproduced just using the quokka file above
(for example because it requires/imports some files from your project),
please create a small repository where the issue can be reproduced.

Thanks for reporting the problem. Unfortunately we could not reproduce the issue but we have released a new version of Quokka for JetBrains IDEs that we expect will fix your problem (v1.0.223). Please let us know if you continue to experience the issue after the update.
