C++/Win32 put_RasterizationScale() - How and where to use it?

[Markromanage]

I have a C++ MFC application that uses an embedded WebView2 browser that causes some users issues when they turn up "Make Text Bigger" setting as show in this issue.

The "Make Text Bigger" setting causes the rasterization scale to change which causes WebView2 to zoom in. I formulated a solution to use put_shoulddetectmonitorscalechanges and add_RasterizationScaleChanged then change the ZoomFactor using put_ZoomFactor to make it zoom out.

I tried to use put_RasterizationScale() but it does not seem to change the rasterization scale. I found #3060 and #2918 that appear to use put_RasterizationScale but I cannot figure out how or where. I tried looking for examples of actual usage of put_RasterizationScale in the WebView2 samples or any example period, but I couldn't find any good example. So, how and where can you use it?
