Edit Manipulators have Wrong Orientation with Local Ruler Mode on Linked Objects

Repro:

• Open Build mode, Edit mode (Ctrl-3), and set the Ruler mode to "Local".
• Rez two prims.
• Rotate the second prim to be different from the first.
• With the second prim selected, observe that the manipulator arrows are oriented to the second prim.
• Close and re-open Build mode to clear the object selection.
• Select the second prim.
• Hold shift and select the first prim. Both prims are now selected.
• Link the two prims to form one object.
• Observe that the manipulator arrows are oriented the same as the root prim (the first prim, unrotated).
• Close and re-open Build mode to clear the object selection.
• Re-select the linked prims.

• Expected: the manipulator arrows should be oriented to the root prim.
  = Observed: the maniputalor arrows are oriented to the NON-root prim.

This works for any number of prims in a linkset. The orientation of the edit manipulators will be taken from whichever prim was selected second-to-last before linking. (I think that corresponds to the first non-root prim in the linkset, but I may be wrong.)
