Public bug reported:

Description:

In some cases, text selection doesn't work properly, in particular it's
not possible to drag the selection handles all the way to the bottom (or
the top) if the top (or bottom) of the TextArea is outside of the view.

This bug is partially overlapping with
https://bugs.launchpad.net/ubuntu/+source/ubuntu-ui-toolkit/+bug/1200371
but they're not the same thing.

I have been thinking for a few minutes about what those cases are, and I
came up with the following list:

- If the TextArea is taller than the view, then one part of it will be
out of screen for sure. Let's suppose it's the top side. In that case,
the user wouldn't be able, starting the drag from *within* the view, to
reach the text which is *outside* of the view. This happens, for
instance, in any app which includes a text editor. Once the text fills
more than one page, the user won't be able to select text starting from
anywhere inside the current view, and ending anything outside of the
view. This is probably a very common usecase, together with the second
one.

- If the TextArea is inside a Flickable and that Flickable is scrolled
in a way that partially hides the TextArea. This happens whenever an app
has, for instance, a listview which holds many field of some kind of
forms the user has to fill in. The user fills the visible fields, then
scroll down, thus potentially partially hiding (or partially bringing
into the view) on of the fields.

- If the TextArea is inside a Flickable, which is inside other
Flickables, and they're scrolled in a way that the TextArea is only
partilly into the view. This is the generic case (even though probably
not the most common one).

I'll write my solution proposal in a comment.
