[regression] ComboBox: wrong horizontal positioning when scrolled

[googie]

Problem appears when a page is wider than the screen and horizontal scrollbar is present. If we scroll a page and then click the combobox, the options container is mispositioned. It looks as if it's still in the same place as it was when no scroll was performed - doesn't take scrollLeft into consideration.

ComboBox is positioned well vertically though.

Issue similar to ​http://bugs.dojotoolkit.org/ticket/10581 although seems a bit different, that's why it's been created.

Sorry - wrong component in the ticket chosen. Should be "Dijit" instead of DojoX Form. I cannot find an option to edit bug description, that's why I post this as a comment.

Agreed, it's a different issue. I wonder if the problem is with dojo.position() or something specific to the dijit.popup/dijit.place code.

I was able to reproduce by adding this to _autoComplete.html:

<nowrap>ABCEFGHIJKLMONPQRSTUVWXYZABCEFGHIJKLMONPQRSTUVWXYZABCEFGHIJKLMONPQRSTUVWXYZABCEFGHIJKLMONPQRSTUVWXYZABCEFGHIJKLMONPQRSTUVWXYZABCEFGHIJKLMONPQRSTUVWXYZABCEFGHIJKLMONPQRSTUVWXYZABCEFGHIJKLMONPQRSTUVWXYZ</nowrap>

It's a regression, starting in 1.4.1, from #10581. I'll fix.

(In [22393]) Fix ComboBox drop down positioning problem when:

1. the drop down's width has been increased to match the width of the ComboBox
2. the page has a horizontal scrollbar, and has been scrolled

There's still an issue on IE8 in RTL mode though, listed in #11376.

Fixes #11364, refs #10581, #11376.
