**System Information**
Operating system: macOS 12.0.1
Graphics card: M1 Macbook Pro
**Blender Version**
Broken: 2.93.5 (2.93.5 2021-10-06)
**Short description of error**
I have my startup file set to hide the header in the properties window, and noticed that the Tool Settings tab does not update to show the current tool unless hovered over with the cursor. It updates on tool changes once the header is shown again, and continues to work (even without the header) until the UI is loaded again on opening a file or restarting Blender.
**Exact steps for others to reproduce the error**
Load the UI from the attached blend file and try switching tools in the 3d view's toolbar. Then show the header in the properties window and try switching tools again.{F11701055}
