Isn't this just bug 85631?  I any case, that destcase will likely stop
demonstrating the problem once bug 84582 is fixed (and we will need a better
testcase at that point).

The testcase no longer demonstrates a "continues to block layout" bug now that bug 84582 is fixed, but the throbber does keep spinning until the old load finishes.

What would the "better testcase" described in comment 2 look like and demonstrate?

Comment 5

Not sure that we can do better than the throbber thing, actually.  Not easily.

Attachment: slightly improved testcase

Instead of setting the href to "", which refers to the page itself, set it to a fast (data: URL) thing.  This demonstrates the throbber issue more clearly.

I still see this bug on trunk.

We'd need to keep track of the channel in the element and cancel it to fix this, basically. Not sure how worthwhile that is.
