Quick scroll in contacts sometimes doesn't scroll the content

[Pat McGowan]

Mako running rtm 214

Open contacts
scroll up to reveal the quick scroll letter set
tap on a letter
sometimes the list scrolls to the letter and sometimes it does not move
It seems to do this when the contents are still moving when the tap is done but its not 100%

With silo 036 / ticket 1371 installed, I still see something which looks like this bug.

First I import contacts to fill up the address book with several pages of names. Then if I swipe to start a fast scroll downward, and tap lightly on an early letter like A or B or C, it will sometimes not work correctly. Instead of jumping to the selected letter and stopping, what I see is the letter index highlight moves briefly to what I touched, then goes back down and the page continues scrolling as if I hadn't touched anything.

The only indication that I touched the screen is that the highlight moves to the letter I touched for a fraction of a second.

If I hold the selected letter longer, it seems to function as expected. So, it looks like the bug requires a very quick tap.

Thanks selene for this report, but this looks like a different bug. The bug that was reported here was causing the list to scroll back to beginner afte some secs after open the app. And I confirmed that there is a wrong call of "scrollToBeginner" that was the cause of the problem.

Forget about my last comment the bug that I was thinking while writing it is this one:
https://bugs.launchpad.net/ubuntu/+source/address-book-app/+bug/1488063

They are similar problems but they have different causes.
