Number not taken into account if cursor is still in the field

[FJBDev]

When entering a number if a field area (health coefficient for example), if the mouse cursor is still in the field when clicking on "OK", then the entered number is not taken into account.

Tried to reproduce it but couldn't. I wonder if it's related to the fact that I had just reversed the track (maybe a different bug ?)
Need to investigate more.
