Start the installer activity in new task

The dialog is actually there. You can observe the dialog if you wait
for a while (few seconds).

The activity is actually started (and resumed) right away, but for
some reasons, it is not rendered until a few seconds are passed.
Feel like it may be a bug in in the rendering side...

Work around this by starting the activity in a new task, this is not
something this test is testing for anyway.
