To see what I mean, here's the exact page where I noticed how nicely Chrome handles this situation. https://en.wikipedia.org/w/index.php?title=User_talk:Pomac30&oldid=841031519#Proposed_deletion_of_Kortney_Kane Hovering your mouse over "Kortney Kane" will underline the text. Doing so in Chrome avoids underlining the "y", which would otherwise be partly striked through by the underline. Firefox currently just mindlessly ignores this typography detail. Here's another page I had printed today with Chrome: https://beej.us/guide/bgnet/html/single/bgnet.html It's the table of contents that makes the difference obvious. Wherever text crosses the underline, the underline is interrupted to avoid having a negative impact on legibility. There might be languages (Arabic perhaps?) containing horizontal lines that look really bad when wrongly striked through. Actual results: Expected results:
