Example URL:
https://uk.godaddy.com/help/add-a-subdomain-that-points-to-an-ip-address-4080

Steps to reproduce the problem:
1. Go to https://uk.godaddy.com/help/add-a-subdomain-that-points-to-an-ip-address-4080
2. Scroll up and down the page. Observe that scrolling is very choppy. Scrolling is smooth however in Firefox and Safari
3. Find the `#livechat-compact-container` element in the DOM tree which is a hidden element in the lower-right corner of the page, and disable the `visibility: hidden` rule in the element's inline styles
4. Scroll up and down the page, observe that scrolling is now smooth

A performance profile of the page after step 2 shows regular occurrences of frames where ~200ms is spent in compositing layers. When paint flashing is enabled, scrolling up and down the page continually produces a paint flash for the element referenced in step 3.

What is the expected behavior?
Scrolling should be smooth regardless of the `visibility: hidden` inline style property.

What went wrong?
Scrolling is choppy when the `visibility: hidden` inline style property is enabled.

I tried to capture a static snapshot of the page via File => Save Page As but the element which causes the problem fails to load when the snapshot is opened so the problem is not seen.
