Created attachment 479476 [details] testcase Testcase: <!DOCTYPE html> <meta charset="utf-8"/> <style> annotation-xml, annotation, mrow { font-family: math; display: initial; padding: 50px; border: 1px solid red; background: lightblue; opacity: .8; } </style> <p>Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello</p> <math> <semantics> <mtext></mtext><annotation>annotation</annotation> </semantics> </math> <math> <semantics> <mtext></mtext><annotation-xml encoding="text/html"><span>annotation-xml</span></annotation-xml> </semantics> </math> <p>World World World World World World World World World World World World</p> The annotation and annotation-xml boxes overlap with the "Hello World" text around. Note that the rendering is quite broken. If you remove `opacity: .8` nothing is shown. Also the annotation and annotation-xml text is not visible because of bug 314081.
