I am able to reproduce this bug in Safari Technical Preview 151 and Safari 15.6 on macOS 12.5 using attached Reproducible example, it shows sometime partial text from bottom up and then on refresh show some more and some time does not show at all and on refresh, it will show partial half in one go. In case of other browsers (Firefox Nightly 105 and Chrome Canary 106), this example show all the text in one go in arc shape and does not have same partial text rendering issue as Safari. Just wanted to share update. Thanks!
