Comment 29 for bug 1671799

Made some tests, with both xserver 18 & with/without input-libinput 23 ; and xserver 19 with/without input-libinput 25

To clarify 'mouse': it's a generic usb mouse, no touchpad at all. Tests made on two different ZZ partitions on the same desktop.

Test xserver 18
- note that comment #26 above is a bit confusing: i was talking about the partition using xserver 18
- xserver 18 without input-libinput 23: works well (as previouly said (#23)
- xserver 18 + input-libinput 23: no problem to select a range of calc's cells; but discovered an other 'scrolling' issue when trying to set the 'sort criteria' for keys: scrolling does not work.
That is when using Calc sorting; testing 'scrolling' inside 'nautilus' works well (confusing).
So i purge input-libinput hoping to get back a normal calc's sorting scrolling; that fails; closing calc / restating gnome-shell session / even logout/in the session does not set scrolling back (confusion again); Check System settings mouse options /gnome-tweak-tool but settings are as usual.

- xserver 19 + input-libinput 25 : problem initialy reported
- xserver 19 without input-libinput 25 (23 not installable due to abi, so cant test that case): selecting a cells range can be done as expected, scrolling for sorting also works !!!
