This problem can be replicated by performing a search on Google with JavaScript enabled and the user agent set to WebView Default. Links are presented to the user as `data:image/png` URLs that match the favorite icon for the target URL. If the user selects `Open with Browser` from the context menu Privacy Browser will crash.

Fixed in commit: https://git.stoutner.com/?p=PrivacyBrowser.git;a=commitdiff;h=76eb19024380afb90929e5ef72c650cc18f99c07.

This commit also reworks the WebView.HitTestResult.SRC_IMAGE_ANCHOR_TYPE to pull the link URL instead the data:image URL.
