Grid Expand Doesn't work in IE9 after back navigation

[Joe]

Visual Studio 2010, C#, Telerik 2012.2.814.40

Master page with RadAjaxManager
Content page with RadAjaxManagerProxy

1. Start up - Default Page_Load triggered: Check
2. Expand row in grid - Page_Load triggered: Check
3. Navigate away from page, click back button - Page_Load not triggered
4. Click to Expand row - Page_Load triggered, but row does not expand (this also happens when I try and filter)
5. Click to Expand row again - Page_Load triggered and row expands

This is not an issue in FireFox or Chrome. It seems that when I navigate away from the page with the Grid and click the back button to go back, the Grid won't work the first time (Row expand, filtertemplate, etc..)

Hi Joe,

I tried to replicate the described issue locally by adding a redirect button in the online demo below, but to no avail:
http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/nestedviewtemplatedeclarativerelations/defaultcs.aspx

Please do let me know if you are able to replicate the problematic behaviour in the mentioned demo and if any specific settings are required.

Kind regards,
