Description
When Prototyping something like a FlowDocument i came across an infinite arrange cycle that seems to be caused by border Stroketickness.
<StackLayout>
<Border>
<WebView Background="Red">
<WebView.Source>
<HtmlWebViewSource>
<HtmlWebViewSource.Html>
<![CDATA[
Some HTML
]]>
</HtmlWebViewSource.Html>
</HtmlWebViewSource>
</WebView.Source>
</WebView>
</Border>
</StackLayout>After the html is rendered the Webview gets resized, forcing a layout pass. And than the isse starts kicking in
see the Webview growing
Recording
I guess this is a rounding issue in the calculation when things get close to epsilon...
