Andrew said this may not be reproducible, but if it is, we need to find the regression and kill it.

Could the newly landed <input type=range> support in Gecko cause this?

Rudy, could you land a quick patch on that?

Hi all,

I could not reproduce this issue with the latest v1-train,
https://pvtbuilds.mozilla.org/pub/mozilla.org/b2g/nightly/mozilla-b2g18-unagi/2013/03/2013-03-18-23-02-04/
<input type=range> support is in bug 344618, and I think it has not landed yet.


I guess, this might be one of the regressions that was caused by Settings app. performance improvement.
