Can't zoom on 2D canvases by moving mouse left or right with ctrl+mmb

Broken: version: 2.81 (sub 4), branch: master, commit date: 2019-08-28 20:33, hash: rBa7ac8a22f8eb
Worked: 2.80

Short description of error
In 2.80 you could zoom on 2d canvases like the UV editor or the node editor holding Ctrl+mmd and moving the mouse left or right, or up or down, from the starting point

In 2.81 you can only zoom moving it up or down, left or right doesn't work. This makes it harder with tablets

On top of that, in the node editors, zooming in is slower than before and slower than zooming out, so if you zoom back and forth by moving the cursor between the same two positions, it averages to less zoom instead of zero zoom, which also happens on 2.80 but at a much slower rate

Exact steps for others to reproduce the error
Open a new file, go to the shader editor and try zooming with ctrl+mmb, moving the cursor either side to side and up or down. Compare with 2.80

I can confirm both issues:

  • Can only zoom moving mouse up or down in uniform scale 2D spaces
  • In node editor zooming in is slower than out

The first "issue" is by design, see "Zoom Axis" (Vertical/Horizontal) preference, T65837.

The second is a duplicate of T73575.
