Why disable inherit FontSize?

[RichardRobertson]

I was updating Nuget packages and found that my buttons' content was larger than normal. It took a while to find out that the SymbolIcon was showing the wrong FontSize property and I couldn't figure out why until I found a commit ad81b51 describing exactly what I found.

Is there a change log somewhere that documents this? It was quite unexpected.

Hi, this change is intended, to match the behavior of <SymbolIcon> and <FontIcon> on UWP/WinUI, where:

• <SymbolIcon> has a fixed size of 20, you need <Viewbox> to resize it;
• <FontIcon> has default font size of 20, and not inheriting from parent element.

Sorry this was not documented because it is recongised as a bug (as of to match WinUI behavior). I originally planned to update the README after another epic update, where I will build the font from scratch (instead of grabbing from upstream), to provide better RTL support and add a font variant that matches the appearence (mostly size and stroke width).

Ok, I guess it makes sense from that perspective, but I wonder why the origin chose not to inherit, as is the standard for text elements in Xaml. Thanks.
