This looks like a progression to me. Will check and rebaseline.
Comment 3 Ben Nham 2020-03-05 10:26:38 PST 
This test has been flaky on Mac with the exact same diff in the past, and we marked it as such:

Comment 4 Ben Nham 2020-03-05 13:04:29 PST 
After talking to Alan and Jacob, the plan is to mark this as flaky on iOS as well, and change the expectations file to reference the older bug (https://bugs.webkit.org/show_bug.cgi?id=204312) to investigate why the SVG render tree output has 0w/0h but non-zero size output in certain cases.
