[regression] With Dojo 1.9.2, pages are jumping to the bottom after onload in Chrome

[Cormac Flynn]

Hey,

I have a strange issue that has arisen since updating to Dojo 1.9.2; upon page load, the page is jumping to the bottom.

This happens consistently and only with Dojo 1.9.2 on Chrome - if I downgrade to 1.9.1 it never happens, and I don't see it at all on Firefox.

I've commented out all Dojo dependencies and reintroduced them one-by-one, but the problem doesn't appear for any one module in particular. For example, it happens when I include dojo/topic or one of the dom modules, but not if I only include dojo/_base/window.

I understand this bug report isn't must use without more specific steps-to-reproduce; I'll work on a test case when I have a moment. But it is happening consistently, and disappears when I downgrade.

Are there any pages within the Dojo tests where you also see this in action?

[Cormac Flynn]

I haven't yet had a chance to test; I'll have some time later in the week to try to narrow it down further

This is going to be caused by the changed focusin event detection in dojo/on, though it should not cause such a behaviour since the test is designed to use an element that is viewport-fixed so should not cause any scrolling.

Aargh. I've just reported #17645 then discovered this ticket. Yes there's position: fixed on temporary element but looks like Chrome ignores it when no coordinates are provided as well. So as I wrote in #17645, it can be fixed by adding in dojo/on.js following code on line 20:

  element.style.top = '0px';
  element.style.left = '0px';

#17645 is a duplicate of this ticket.

Colin, this is from your 2536e5cd0935cc7356d584bab6ac2c73d3ad6164 (refs #17599).

[Colin Snover]

I’m having trouble reproducing any issue with the event-focusin test case. Can someone provide a modification to that test case that demonstrates this issue?

[Colin Snover]

Never mind, I was able to reproduce it. Sorry for the trouble. Fix forthcoming.
