Report jump: put the mouse pointer on the end jumped to

A double click on a linked folio report showed the other end's folio
and highlighted it, but left the mouse pointer where it was, on every
platform, while only Wayland forbids a program to move it. On Windows,
X11 and macOS the pointer is now put on the end jumped to, once the
folio shown has its size (next turn of the event loop), so that a
second double click jumps back. On Wayland the highlight alone still
shows where the jump landed.

The pointing hand over a report's label text also stayed after a
click: mousePressEvent() puts the text colour back, and the cursor was
only unset with the colour in hoverLeaveEvent(). It is now always
unset when the mouse leaves the text.
