IE9 and embedded dojo page within an iframe: scrollIntoView fails, thus selecting entries from a FilteringSelect not possible

[Paul Christopher]

Description

Dojo throws an exepction in dojo/window.js after having processed line 90 when trying to scroll a node into view: "Error: scrollIntoView: Access denied".

This is quite a blocker since scrollIntoView is used by _ListBase to select an item e.g. in a drop down of a FilteringSelect. And if a webpage embeds another webpage using an iframe, the FilteringSelects of the embeded page do not work properly.

Steps to reproduce the issue

• Unzip the attached testcase. Run testFilteringSelectFrame_ERROR.html which actually embeds testFilteringSelect.html.

• Open the drop down by clicking on the arrow icon with your mouse. This already triggers the above error.

• Next grib the handle of the drop down's scroll bar with the mouse and scroll down to the very end.

• Try to select the last item: This does not work. Spurious scroll events make it nearly impossible to select an entry.

• Next run the file testFilteringSelectFrame_OK.html. There are no errors. Everything works fine. The only difference between those two files is that the latter uses src="testFilteringSelect.html" to embed the test page containg the FilteringSelect, the former, error prone page src="​http://127.0.0.1:8080/TestLoader1-7-2/testFilteringSelect.html"

Discussion

No idea why the url makes a difference. However an embedded dojo page should work always like a charm regardeless who embeds it?

Affected browser

IE9 only

Doug, can you take this one, since it's about scrollIntoView()?
