Details

When you try to load a data image URL like "data:image/png;base64,42" the navigate / get method hangs because Marionette thinks a load event is expected but none seem to happen. Could it be that there is no load event for such URLs? Also whats the difference to "data:text/plain" which works fine? Mike, do you have an answer for the above? If not, do you know someone who could help us?

Hm, as it looks like it is the base64 part in the data URL which is causing this hang. When I use the following URL Marionette also hangs in waiting for the page being loaded: "data:text/plain;base64,42".
Well, it looks like that this behavior exists for all but "data:text/html". Maybe we should only expect load events happening from text/html but no other MIME type?
Summary: Navigate / get hangs for data image URLs → Navigate / get hangs for data URLs in waiting for a load event
This is related to https://bugzilla.mozilla.org/show_bug.cgi?id=1322772. Non-HTML documents does not produce DOMContentLoaded events that we wait for. I have written a patch for image documents specifically, but if data:text/plain;base64,42 is exerting the same problem we should likely consider fixing it in a more generic way.
