wxAUI: minimized pane restore tab missing in 3.3.3

Hi,

I think there is a regression in wxAUI between 3.3.2 and 3.3.3.

In 3.3.2, when I minimize an AUI pane using the _ button, the pane disappears and a small tab with its icon/title appears, allowing me to restore it.

In 3.3.3, the pane disappears as expected, but the tab is no longer visible, so there is no way to restore the pane.

I reproduced this with the official samples/aui example, built with Visual Studio 2026 on Windows 11.

3.3.2 → works 3.3.3 → pane disappears, but the restore tab is missing.

Thanks!
