Showing datagrid title tooltips when hovering anywhere in title cell

Hi, I'm just wondering if it's possible to bring up the tooltips for column headers when the mouse goes anywhere inside the cell - not just when hovering over the actual text. Currently the tooltip is applied directly to the span containing the text (and I see why this would be the desired behaviour most of the time), but for my use case it would be very useful if it were applied to the th containing the span.

Are there any workarounds possible, or could an option to change this behaviour be added to the library?

Thanks

There is a HeaderCellRender callback that can be used to set header cell attributes like title.
