Telerik Q1/2016 but this rendering behavior is the same in previous versions of Telerik.
I have RadGrid in a <TD colspan="3">. After postback the radgrid appears above the <table>.
Issue occurs with Chrome 47.0.2526.111 and IE 11 (when Edge mode is used).
It only works fine with content="IE=EmulateIE8".
VS2015 SP1, no other HTML syntax errors. Using AjaxManager.
