Not sure if this is intended behavior, this is a follow up to comment 2 of bug #1289943.

A minimized construction window will get automatically maximized when construction ends.

Steps to reproduce:
- start a game
- place a building
- click on building to open the construction window
- CTRL+click on the title to minimize it
- wait for construction to end
- you'll see the window get maximized
