PTAL

[Mike West, 2014-11-26 08:00:36]

Any idea what the usage is?

[philipj_slow, 2014-11-26 08:15:21]

No, there are no use counters for this. For comparison,
https://codereview.chromium.org/133683004 made the same change for getAttribute,
getElementsByTagName and other methods which are certainly in wider use. There
was a hickup with setAttribute, but I think only actually making the change will
reveal if there are problematic sites.

Alright. Let's break things: LGTM.
