@colinwalker I'm wondering if also applying ‘-webkit-border-radius’ might work - I dealt with a different safari bug recently using a similar solution.
@colinwalker I was curious about the bug and played around a little. Something I tried worked though I wouldn’t really call it a solution. I thought you might find it interesting though – I pasted the contents of my test file at https://passtext.in/9850859070#ODgWNSmshbJYYOlVqaLJ (expires in three days).
