Jquery scrollTop causes "Uncaught object "[object Object]" was thrown. Throw Error instead."

[enes1004]

What is your Test Scenario?

I am trying to test a simple click in a page with jquery function scrollTop()

What is the Current behavior?

The page scrolls to destination.
TestCafe waits for element to appear and then throws
"Uncaught object "[object Object]" was thrown. Throw Error instead."

If I exclude scroll functions, test works. If I use native JS, it works in Chrome. (But, scrolling had browser compatibility issues with other browsers, so I prefer to use Jquery ScrollTop)

What is the Expected behavior?

Passing test as there is no assetion

What is your web application and your TestCafe test code?

Hi @enes1004

Thank you for the detailed description. I've reproduced the problem.

For team:
The problem is in styleUtils.setScrollLeft function. We should use the native functions window.scrollTop, window.scrollLeft.

Thank you very much. I will be watching for update.
