Skeletal Mesh Component Anim to Play Window Too Small

In an Actor Blueprint, in the Skeletal Mesh Component's detail panel, the "Anim to Play" window is too narrow and only shows a small portion of the selected animation name. (See attached image.)

Regression: No

1. Open any project in UE415 or earlier
2. Create a new Actor Blueprint
3. Add a Skeletal Mesh Component
4. Select a skeleton in SKM Component's detail panel
   RESULT: in the Animation section of the Details panel after selecting "Use Animation Asset" the window for the "Anim to Play" remains very narrow, making it hard to see the name of the selected animation asset.
   EXPECTED: The "Anim to Play" window to be wide enough to enable the user to tell which animation is currently selected.
