PCBNew — Can't change grid size, stuck on 2.54mm

[Antoine Pintout]

Can't change grid size in PCBNew. Stuck on 2.54mm.
It happens in new or existing projects.

Step to reproduce :
— In a new project : open a board file.
— Grid is 1.27mm.
— Select 0.5mm from the grid sizes dropdown menu (or any other value).
— Grid size should be 0.5mm, instead it is 2.54mm

Pcbnew: Using the toolbar combo box 2.54 mm (100.00 mils) is always selected no matter what setting you choose.
Workaround: use the right click context menu to change grid.

In the footprint editor there seems to be a sync problem between right click context menu and toolbar combobox. Using the toolbar combobox you can only decrease from the current grid size, right click context menu can choose any grid.
