When the side pane is detached, hitting "F11" can close the pane, but won't re-open it. You have to use the menu "Edit->Styles" to open it again.
Found in 6.0.6.
Not found in 5.4.
We didn't test intermediate versions.
Steps to Reproduce:
1. Detach the side pane
2. Close it (either by mouse or using F11)
3. Hit F11
The pane does NOT open
The pane should open on the "styles" tab. This is what happens in 5.4.
