Zoom in using pinch-to-zoom on precision touchpad or using ctrl + +.
"Pinch-to-zoom on touchpad" and "ctrl+plus" do different things with apz.allow_zooming=true: the former only scales (the new feature enabled by apz.allow_zooming), while the latter scales and reflows. You probably don't want to be mixing them.
Website after zooming is not in "normal" (100%) zoom level.
Do you mean it's at a smaller zoom level than 100%?
Can you get to the smaller zoom level from the initial state by pinch-zooming out?
Can you give an example site where this happens?
Do you mean it's at a smaller zoom level than 100%?
It's bigger than should be.
Can you get to the smaller zoom level from the initial state by pinch-zooming out?
Yes, and again, if I zoom it to 100% level, website still is in bigger state.
I recorded a video to better describe the issue: https://streamable.com/djn4b
On the video, I'm zooming using pinch-to-zoom on touchpad.

Ah, right. On Windows, APZ zooming is not hooked up to touchpads yet, only touchscreens. As a result, the pinch gesture shown in the video is still performing the old-style reflowing zoom.
Supporting Windows touchpads is tracked in bug 1568676.
