Steps to reproduce the problem:
1. Create an element with the CSS style position: sticky; top: 0.
2. Place a select element with some options within the sticky element.
3. Scroll down the page until the sticky element sticks to the top of the page.
4. Click on the select element.

What is the expected behavior?
Clicking on the select element should reveal the options.

What went wrong?
Clicking on the select element reveals the options, but the page scrolls back to where the sticky element was originally rendered on the page.

Did this work before? N/A 

Does this work in other browsers? Yes
