We were mimicking Firefox' behavior that whenever a programmatic change to an <input>'s or <textarea>'s selection happened, the new selection focus is brought into view by scrolling. Currently we run a layout update synchronously for that to make sure we have the fragment's correct dimensions, which caused a significant performance regression in Speedometer. Since this is non-standard behavior, let's mimic Chromium instead which does not scroll at all - only for direct user initiated input such as typing.
