 In certain circumstances moving with the arrow keys changes tags. This was
 reported in ticket 3700 but this was closed as non-reproducible.

 I get the error in very specific circumstances, usually with ways.
 Scenario: modify tags in a way using the 'r' key, then immediately push an
 arrow key. The highway tag will change as if the arrow key was used on the
 menu (e.g. if you had a minor road and you push arrow right, you get a
 residential road). Strangely enough it does not happen in the very
 beginning of a session. I strongly suspect the behaviour occurs only if
 the menu in question has been used in the session. I just tried the
 following:
 -open Potlatch 2
 -click on an existing highway=residential
 -create new way, apply 'r' and arrow left (no change)
 -change highway tag using the menu to highway=unclassified
 -create another new way and apply 'r' making it also
 highway=unclassified
 -push arrow up. The new road now has highway=secondary.

 The bug also affects nodes (but I have no systematic knowledge of that)
 and also occurs if you push an arrow key directly after cutting up a way
 with 'x'.
