Created attachment 131182 [details] Demo on contenteditable selection range issue Please try running the sample HTML given in the attachment. Firefox 10.0.2, InternetExplorer 9 and Opera 11.6 selects `ob`; while WebKit only selects `o` in the two instances. If both parent and child tags have the same contenteditable property (ie. true or false) it will select `ob`.
I am not able to reproduce this bug in Safari 16.2, STP 159 and it selects "ob" and it matches Chrome Canary 110 and Firefox Nightly 110. Since all browsers are matching, I am going to mark this as "RESOLVED WONTFIX" since it was not confirmed earlier.
