Exception with long Image URIs

Hi Xamarin Team,

In a View Model, I declare a string-type with a long url of an image (imagine a source with a resource-token and some resizing query strings).
During runtime, the following exception occours and crashes the app instantly in iOS and maybe other platforms as well (too long path for FileStream).

I'm not sure about the internals - but it might be related to the caching of the image? or to a fallback to search the image on the local file storage instead?
Would be great if you're able to workaround the crash in a upcoming release even if such images would not be cached in a first step.

thanks in advance and best,
Adrian
