“To start creating categories..” text overlaps with the Categories text and the “+” button when the Sprite Library Editor window is docked and resized

Steps to reproduce:

1. Create a new Unity project using the Universal 2D template
2. Open the Sprite Library Editor window (Window > 2D > Sprite Library Editor window)
3. Dock the Sprite Library Editor window
4. Click the "Create new Sprite Library Asset"
5. Resize the Categories tab by drag clicking the slider all the way to the left
6. Resize the Sprite Library Editor window vertically to be smaller
7. Observe the Sprite Library Editor window

Actual results: “To start creating categories..” text overlaps with the Categories text and the “+” button

Expected results: No UI elements overlap
