Description

If I define a new headerCellTemplate after the grid has been rendered, should gridApi.core.refresh() apply the new headerCellTemplate?

Research direction
Investigate the gridApi.core.refresh() method and how it applies headerCellTemplate changes. The issue suggests that dynamically defined headerCellTemplate is not applied after refresh. Look at the source code for header rendering and column definition updates. Consider that the issue is from 2015 and may be resolved in later releases.
