Created attachment 333481 [details] CSS Quotes Bug Demonstration Observe the attached file when served over file:// or over http://localhost, as well as https://jschoi.org/18/webkit-quotes-test and https://codepen.io/js-choi/pen/wyJaaG. In all four, the quotation marks below surrounding .y (i.e., open-quote and close-quote) should be asterisks (*…*). However, when served over file:// or http://localhost, they appear as straight quote marks ("…"), and when served over https:, they appear as curly quote marks (“…”) (cf. this page hosted on https://jschoi.org and this page hosted on CodePen). No matter where it is hosted, the quotes become the correct asterisks (*…*) if the text-indent of .x is changed to zero. This has been tested on STP Release 49 (WebKit 13606.1.3.3) on macOS 10.13.3, as well as Safari on iOS 11.2.5.
The test case works in Chrome and Firefox, but not Safari 15.5+.
