Client-side script: If an error is thrown in a Deferred callback, this error doesn't appear in the console, which makes debugging more difficult

CodePen example: https://codepen.io/pomah33/pen/MWrRKMb?editors=0010

If an error was thrown in Deferred callback, this error doesn't appear in console, which makes debugging more difficult

Error possibly was caused by this PR: https://github.com/DevExpress/DevExtreme.AspNet.Data/commit/6d973700bd28e4440aa05e267fb255202b87d395#diff-24d8a479ae56566c65690364aa2156fff7613fd38bd024153579f15d92b26f91L73, when deferred-like method .done was changed to promise-like .then

But on error in 'then' section of deferred (not promise) hides without appearing in console

Samples to try in dev console:

new Promise((resolve) => { window.r1 = resolve; }).then(() => { throw new Error('my error'); })
r1()

const d = new $.Deferred()
d.then(() => { throw new Error('my error'); })
d.resolve()

Start with the CodePen example and the two console samples comparing native Promise.then with $.Deferred().then. Review the linked commit where .done changed to .then and trace how errors from the callback are handled. Done means an error thrown in a Deferred callback appears in the browser console.
