In https://bugs.webkit.org/show_bug.cgi?id=47666 we rolled back a more strict version of base64 decoding added in https://bugs.webkit.org/show_bug.cgi?id=44261 because the test LayoutTests/editing/undo/orphaned-selection-crash-bug32823-2.html started to fail. As commented here https://bugs.webkit.org/show_bug.cgi?id=47661#c10 the actual problem was not the test but the new code in ResourceHandleSoup.cpp that incorrectly does not finish the load of the dataURL if the base64 decoding fails. We should restore the old strict base64 decoding and gracefully end the load when an error occurs.

Created attachment 70846 [details] Fix for the bug This patch both restores the more strict base64 decoding and it also allows ResourceHandleSoup to properly finish the load of the resource when invalid base64 data is provided.
