Logitech touchpad pinch zoom does not change zoom level
I use Logitech's T650 touchpad, and in Opera, pinch zoom literally zooms the webpage, not change the zoom level in Opera (e.g., 100%, 150%, etc). This literal zoom (I don't know the correct expression) is inconvenient - and in Chrome and Firefox pinch zoom correctly changes zoom level of the browser.
Steps to reproduce: Use pinch zoom in pretty much any website with Logitech T650 touchpad.
Actual result: Website itself gets zoomed
Expected result: It should change the zoom level of Opera.
OS: Windows 10 64bit
Version of Opera: 40.0.2308.81
