Created attachment 462386 [details] HTML file reproducing the issue. STR: 1: Open attachment: setbaseandextent_not_setting_focus_as_requested_repro.html 2. Click the "Generate selection" button. Expected results: On-screen logger should report the resulting selection, which reflects the focusNode and focusOffset passed as parameters in the call to Selection.setBaseTextAndExtent(): { "focusNode": "#text:Text outside:", "focusOffset": 13, "anchorNode": "#text:_", "anchorOffset": 1 } Actual results: On-screen logger reports a different focusNode and focusOffset (the start of the text node from the neighbouring element): { "focusNode": "#text:_", "focusOffset": 0, "anchorNode": "#text:_", "anchorOffset": 1 } Firefox and Chrome produce the expected results.

Spec: https://w3c.github.io/selection-api/#dom-selection-setbaseandextent Tests: https://wpt.fyi/results/selection/setBaseAndExtent.html?label=experimental&label=master&aligned I wonder how reliable the tests are with regards to the current spec.
I think Selection API ‘Live Range’ fixed it since now we are passing all WPT tests cases mentioned by Comment 02 and also in the attached, I am gettign “Expected Result” using WebKit ToT and Safari Technology Preview 165. { "focusNode": "#text:Text outside:", "focusOffset": 13, "anchorNode": "#text:_", "anchorOffset": 1 }
Nice
