I'm a chromium author and wanted to report a Wikipedia bug that was reported to us.
VIew bug: https://bugs.chromium.org/p/chromium/issues/detail?id=756868&
In debugging it seems Wikipedia is using an old version of the jquery scrollTop library. It is broken in the following code:
return this.map(function() { var elem = this , isWin = !elem.nodeName || $.inArray(elem.nodeName.toLowerCase(), ['iframe', '#document', 'html', 'body']) != -1; if (!isWin) return elem; var doc = (elem.contentWindow || elem).document || elem.ownerDocument || elem; return /webkit/i.test(navigator.userAgent) || doc.compatMode == 'BackCompat' ? doc.body : doc.documentElement; });
The test for webkit is wrong now for Chrome 61. I suggest adding:
"if (doc.scrollingElement) return doc.scrollingElement;"
condition before return or upgrading to a newer version of jquery scrollTo
