Description Simon Pieters (:zcorpan) 2016-04-12 03:30:23 PDT 
See https://github.com/whatwg/html/pull/1006

var input = document.createElement('input');
input.type = 'checkbox';
input.selectionDirection; // should return null
input.selectionStart; // should return null
input.selectionEnd; // should return null

I am not against this change but I am slightly worried about backward compatibility here. I think I'll wait a bit before implementing this.

Chrome 52 and Firefox 47 still throw in this case.

I am not sure whether I am testing correctly here but when I copy the following snippet from Comment 0 into JSfiddle, I get following behavior across browsers:

Link - https://jsfiddle.net/sun1vzxq/show

*** Safari 15.6 on macOS 12.5 ***

Error in console - "<a class='gotoLine' href='#43:6'>43:6</a> TypeError: Type error"

*** Firefox Nightly 105 ***

No error in console

*** Chrome Canary 106 ***

No error in console

Just wanted to share updated results. Thanks!

It seems this is fixed in Safari TP 148 (Safari 16.0, WebKit 17614.1.17.1)

Indeed, it is fixed in Safari Technical Preview 150. Thanks for bump simon@bocoup.com.. I am going to mark this as "RESOLVED CONFIGURATION CHANGED".
