[regression] Cut/Copy/Paste options displayed off the top of the screen from the addressbar

This is a rather recent regression, most likely in the UITK (as the issue is not present on RTM, although webbrowser-app was recently synced back from vivid to RTM, so both versions are virtually identical).

I can easily reproduce with the following standalone test app:

import QtQuick 2.0
import Ubuntu.Components 1.1

MainView {
    TextField {
        anchors {
            top: parent.top
            left: parent.left
            right: parent.right
            margins: units.gu(2)
        }
        focus: true
        text: "long-press me to invoke contextual options"
        Component.onCompleted: selectAll()
    }
}

I can confirm i'm seeing this too on Vivid-proposed #72.

Status changed to 'Confirmed' because the bug affects multiple users.

Screenshot of bug

Confirmed it's a regression in UITK, I'm in the process of tracking down the change.

FTR offending change is http://bazaar.launchpad.net/~ubuntu-sdk-team/ubuntu-ui-toolkit/staging/revision/1371 and I'm working on a way to test the positioning in code (the test case I have relies on the human eye to see the bug), and afterwards will look into a fix.

This also seems to be the cause of the dash search history appearing off-screen.

This bug was fixed in the package ubuntu-ui-toolkit - 1.2.1433+15.04.20150306-0ubuntu1

  * Second stage of simplification - divider group property is an item,

    not backup the property binding, uses QQmlPropertyPrivate::write()
    with parameter to keep bindings. ListItemAnimator uses behavior to
    animate snapping. Styling got "styledItem" context property to obey
    general styling rules. clicked() and pressAndHold() emission fix
    when content is swiped.
  * Transferring the ListItem attached properties to ListItemStyle API.
    Most of the style API became redundant, and removed. Few API from
    ListItem were also removed as not needed. ListItemAnimator,
    UCListItemAttached and UCActionPanel classes removed.
    Panel swiping overshoot made elastic. Snapping animation transformed
    into SmoothedAnimation, uses velocity of 60GU/second. Turning
    warnings to be reported in the error property.
    SHOW_SERVICEPROPERTIES_WARNINGS environment variable set will
    display them in the console. Fixes: LP: #1423203.
