Blender Version
Broken: version: 2.83 (sub 2), branch: master, commit date: 2020-02-03 17:41, hash: 03a29090b5
Worked: never worked properly in 2.8x

Short description of error
Using Ctrl+MiddleMB we can zoom in and out in a lot of areas from editors to toolbars, however zooming out goes a lot faster than zooming in, for example the 3D view works fine but not the toolbars or properties shelf.
Sorry for the video but i don't have a better way to explain it

Exact steps for others to reproduce the error
Try to Zoom in any toolbar or the properties editor using Ctrl+mmb and look carefully how much do you move the mouse up and down.

Also there seems to be no way to reset the zoom for many editor panels

You should be able to reset the zoom with Home

Changing the zoom axis from vertical to horizontal helps but that is not as comfortable in the 3d viewport.

This issues depends on the aspect ratio of the editor, so if you have a square view, the zoom in and out is quite uniform.
But if the view is rectangular then zoom in is much slower than out.

I tried this quick hack and it solved the issues:

However MOUSEZOOM (trackpad pinch) is very slow.

Related to this issue, zooming in and out in the Cycles node editor is really slow with pinch gesture on a Mac trackpad. Zooming in is painfully slow and zooming out is somewhat okay, but could still be way faster without being uncontrollably fast.

@JoelArt You would need to test the current version under development, daily build of version 2.93 , that includes the patch. If the problem still occurs in that version, please create a new bug report.

Tagging on this platforms works by using @ followed by the username. So to notify me you would type @rjg.
