An exception is thrown on setting the Grid column HeaderTemplate

Bug report

Regression in R1 2023 SP1.

Reproduction of the problem

Set a HeaderTemplate in one of the following 3 ways.

columns.Bound(p => p.Freight).HeaderTemplate("<div title='Freight'>Freight</div>");
columns.Bound(p => p.Freight).HeaderTemplate(@<text>
<div title="Freight">Freight</div>
columns.Bound(p => p.Freight).HeaderTemplate(@<div title="Freight">Freight</div>);

Current behavior

In the first scenario the error is:
System.NotSupportedException: Specified method is not supported. 

In the second and third scenario the error is:
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Expected/desired behavior

No exception thrown when the HeaderTemplate is set.
