Link in Confluence pages cannot be edited in IE9, IE10 & IE11 when Page Layout is in used

Steps to reproduce:

1. Access Confluence in IE browser
2. Create a Confluence page
3. Insert Page Layout e.g. Three columns
4. Add text to all elements, add some links to that text.
5. Save the page
6. Edit the page. Editing of the links on top will work ok.
7. Scroll down. Editing of links is no longer possible, the menu (Go to link, Edit and Unlink) are not displayed. The layout flickers when links are clicked.
8. See the screen cast for details: http://screencast.com/t/Y42hyAaiPFo
9. Same issue is not observed without the use of Page Layout in IE
10. Here's a sample space xml backup from a freshly installed Confluence 5.0.2 that represents the problem: ds-152558-6.xml.zip - sample taken from Demonstration Space

Workaround:

1. Edit the links using Confluence Source Editor in IE browser
2. Use Chrome or Firefox browser instead

Note:

Upon further research, I found out that the issue only occurred when you have to scroll down the page to edit the links. It seems that when the page layout height is more than the default editor height (the need to scroll down the page), problem exist.

Root Cause

The underlying problem is that Internet Explorer fires a scrolling event sometimes when the link is clicked, which results in the property panel being closed (which when scrolling normally is what is expected).
