Steps to reproduce the problem:
1. html must contain an element (e.g. <div id="foo">)
2. the element must be styled with CSS meeting all of the following conditions (e.g. #foo { ... })
3. background-image: url(); - the image file must be very tall.  I haven't tested all heights.  but 1080x5000px reproduces bug
4.  height: >= 3970px (bug not reproduced at <= 3960px)
5.  background-size: >= 101vw (bug not reproduced at <= 100vw)
6.   background-position-y: <= -495px (bug not reproduced at >= -490px)

What is the expected behavior?
when the HTML file is loaded by the browser, the element's background-image should be visible

What went wrong?
when the HTML file is loaded by the browser, the element's background-image is invisible
