Expected behavior:

  • Inspect shows a correct accessbiility tree for a ToolStrip with a ToolStripControlHost:

Minimal repro:

  • Create a .NET 6.0 app
  • Add a ToolStrip to the app
  • Create ToolStripControlHost with some control (eg. new ToolStripControlHost(new RadioButton())) and add it to the ToolStrip items
  • Add several any items to ToolStrip (optional)
  • Run the app and check the accessibility tree using Inspect
