Karl, Your screenshot is very useful and interesting. I can see many differences; some are small but nevertheless there are differences. Firefox under Linux (I can upload a screenshot if needed, if requested) renders the test quite differently from Firefox under Mac; it's not just colors but also line spacing (white areas) and height of background painting. Chrome under Mac and Chrome under Linux will select the <br> element; Safari and Firefox under Linux and Mac do not do that.

The original test has been split into 2 separate, distinct tests. Apparently, Safari 175 Technological Preview on macOS 13.5 passes both tests: https://wpt.fyi/results/css/css-color/system-color-hightlights-vs-getSelection-001.html?label=experimental&label=master&aligned https://wpt.fyi/results/css/css-color/system-color-hightlights-vs-getSelection-002.html?label=experimental&label=master&aligned Therefore Resolving as FIXED
