Broken: version: 2.83 (sub 2), branch: master, commit date: 2020-02-03 17:41, hash: rB03a29090b57d
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.
