Created attachment 478846 [details] Example of layout bug https://theradavist.com Under each article, on the lower right corner, there's an svg graphic of a small voice balloon, with the number of comments of each article inside. In other browsers (Firefox, Chrome), and in previous versions of Safari, this displayed correctly - the text was nested inside the svg. Now, as of MacOS 26.4 Safari, these elements are stacked vertically on the page.
