I ran into this same problem when working on the "auto focus" forms feature in b2g where scrollIntoView(true) would put the device in a broken scroll state ( will attach an image ). Is there some rational that makes true better then false? If not false works better... Sadly I don't have background why it is this way yet.

Image example- this can happen in other cases... I will try to figure out what causes this and hopefully file a bug to either fix this or write a marionette server test to cover the case.

Malini or David could likely answer this better than I.

Comment on attachment 799901 [details] [diff] [review] turn scrollIntoView to false Review of attachment 799901 [details] [diff] [review]: ----------------------------------------------------------------- Just intuitively, this change makes sense. I'm going to make a try run and see what happens.

This patch didn't apply cleanly, which resulted in a no-op try run. I've fixed that, and pushed to try again: https://tbpl.mozilla.org/?tree=Try&rev=922e6cb74eb6

try run is green, let's ship it!
