Subject: [PATCH] QIOSTextInputOverlay: listen for selection changes, also for
 Qt::ImReadOnly
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The focus object can emit selection updates (e.g from mouse drag), and
accept modifying it through IM when dragging on the handles, even if it
doesn't accept text input and IM in general (and hence return false from
inputMethodAccepted()). This is typically the case for read-only text fields.
So we should listen for selection changes and enable handles also for
this case (unless the IM hints tells us explicitly not to use handles/edit menu).

Fixes: QTBUG-91545
