Disabling auto focus on numerical inputs [upstream]

[ceremcem]

Do you think disabling auto focus on numerical inputs which causes accidental data changes is hard to implement? It's clearly an upstream bug, but here are some promising searches: https://forum.freecadweb.org/viewtopic.php?f=3&t=30772

I think it is a much less a problem in my branch, as every property change using property editor is undoable.

every property change using property editor is undoable.

A property change is undoable if and only if we notice the change (while scrolling in the property window, a change might be missed)

I have changed property editor behavior. Please try it. If it works well, I'll submit a PR upstream.

According to first tests it works nicely.

My reproduction steps for the old behavior are as follows:

1. Click an object (A), navigate property window, change its Placement.x
2. Click another object (B)
3. Scroll down and up in the property window
4. You'll accidentally change B object's Placement.x eventually
5. Same goes for any newly clicked objects

With this patch this behavior seems to fixed and if you click to edit Placement.x and then another object (or outside), the focus is removed from the input which makes further navigation safe.

Thanks!
