Created attachment 303070 [details] Testcase This testcase renders differently from Chrome and FF: <!DOCTYPE html> <html> <head> <style> option { border: 2px blue solid; } </style> </head> <body> <option>Test</option> </body> </html>
This makes a display:block <datalist> with <option> children render differently from Chrome and Firefox.
<option> element not displayed at all in the Safari 15.5 (16613.2.7.1.9, 16613) Even display: block not helps
So we don't match Chrome or Firefox at this time.
