Summary border-image-slice distorted when using with border-width

Created attachment 437145 [details] Browser screenshots `border-image-slice` in all other browser rendering engines maintains aspect ratio and displays more or fewer of the `border-image` as the `border-width` increases or decreases. Only on WebKit, does the `border-image` stretch/squish and distort the aspect ratio rather than displaying more or fewer `border-image` instances. This can be reproduced reliably in any environment, and can be seen on the MDN docs page for `border-image-slice`. Scroll down to the interactive preview and drag the `border-width` range slider handle either left or right while keeping the `border-image-slice` handle stationary at 30. In Safari/WebKit, you will see the `border-image` become distorted, whereas in other browsers you will see the border shrink or grow and fit in more or fewer `border-image` instances. MDN `border-image-slice` example intrapage link: https://developer.mozilla.org/en-US/docs/Web/CSS/border-image-slice#result — I have attached screenshots of WebKit vs. Firefox/Chrome.
