> Please don't touch to decodeURLEscapeSequences, a data uri scheme might contain escaped characters, this is the spec. See my comments about that in the following bug https://bugs.webkit.org/show_bug.cgi?id=119423

As you can see in https://bugs.webkit.org/show_bug.cgi?id=121609 , decodeURLEscapeSequences is currently breaking existing content of the form of <img src="foo%3Fbar.gif">
OTOH, you have encoded data URIs, which aren't supported in <img src> in neither Gecko nor Blink (and weren't supported in WebKit before the srcset patch), for which there's no existing content you may break.

If you believe encoded data URIs should be supported, they should be supported for all URLs, not only for img, and not with the price of breaking existing content.
