This behavior exists in v1. The above steps can be done against the beedemo URL to get the same jumping behavior with FF.
scrollIntoView at ln 1367 of hudson-behavior.js does not correctly calculate the page size after things have been opened, and thus scrolls the window to the wrong spot. The easy fix is just to remove this behavior. Perhaps a better fix would be to fix the math, but I am not convinced that really is the right behavior and I am not sure how best to jump through those hoops, in prototpye.js with who knows how many page shape changing events may happen on the page.
So far cannot reproduce with OSX Chrome Version 49.0.2623.87 (64-bit)
