[macOS] canvas not cleared of previous drawings on desktop

[spouliot]

Current behavior

From #16690 (comment)

updates on live charts do not seem to clear previous drawings (unless a redraw is made)

@spouliot On the LiveCharts side, clearing the canvas is something we do depending on the UI framework, some frameworks require it, some frameworks don't.

In the specific case of Uno, all the supported platforms do not require to clear the canvas, but on catalyst it seems that it behaves different, should this be handled in the LiveCharts side?

Expected behavior

This should be identical with other Uno backends

How to reproduce it (as minimally and precisely as possible)

The LiveCharts sample was showing the issue (see original issue)
