Describe the bug
Wrap a Layer in a RasterizingTileLayer. Consider the following code

Map _map = new();
Layer _layer = new() 
{
     Style = /* Style 1 */;
     DataSource = /* DataSource 1 */;
};
RasterizingTileLayer _tileLayer = new(_layer);

Later on you want to update the style and data source of _layer, e.g.

_layer.Style = /* Style 2 */

_layer.DataSource = /* DataSource 2 */

_tileLayer.ClearCache();
_map.Refresh();

The style will be correctly updated to Style 2 but the data source will remain DataSource 1. I provided a minimal example below.

To Reproduce
Steps to reproduce the behavior:

1. Clone https://github.com/Thoronion/MapsuiSandBox
2. Checkout branch datasource_not_updating
3. Click on the test button
4. Only the style is updated and not the data source.

Expected behavior
Expecting the datasource to be updated and rendered.

@inforithmics Is this something you could look at?
