### Description of the bug

Regular glass sheets cannot be used to put a pane of glass in a window. Regular glass windows exist at roundstart, but cannot be created.

Reinforced glass, however, can be used for this purpose. This bug has existed for many years.

### What's the difference with what should have happened?

Regular glass sheets should create a window in a window frame.

### How do we reproduce this bug?

1. Construct a window frame (or use a pre-spawned one, no difference)
2. Try to use a stack of glass sheets on it
