In this case you got me... what sense does it make? If there is no
reference to original blob or any other object using that URL, why is it
kept?
Because given a string there is no way to tell whether someone has a
"reference" it.
Consider this:
window.myStash = URL.createObjectUrl(blob).split("");
img.src = window.myStash.join("");
// much later one
otherImg.src = window.myStash.join("");
This is a simple case, of course. The url could be stored in all
sorts of other ways, because strings are very very mungable from JS.
Sorry, of course I understand, we do not only have arbitrary string
created by this method, but there can be Blob itself hanging in memory...
well 3 options are here
1/ leave URL revokable (affecting blob)
2/ create something like Blob.dispose() (affecting URL)
3/ assign blob to media element (but I do not like the SRC attribute for
that, and it causes issues with HTML source text)
nice :)
