Picklist outside the screen

When I’m coding in the lower edge of the code editor and the picklist appears I can´t see the columns outside the screen. Using the up and down arrows I can move between the columns but I can´t see it. This happens because the table has many columns and the picklist is too large…

This bug was fixed till version 12.6 but reappears once again en version 12.7

What happened with the fix?

I made a post of this en Aug-2014
