PatternNotSupportedException when trying to access Tree UI element

[agagalski]

When trying to access (Get, Click, Expand, Select Collapse ...) Tree UI item (QTreeWidget, Qt 5.x) with any Tree-type keyword library throws exception (#10005, #10010, ...) for example when trying Get All Visible Treeitems Names:

PatternNotSupportedException: The requested pattern 'ExpandCollapse [#10005]' is not supported ---> System.InvalidOperationException: Native pattern is null
   w FlaUI.Core.FrameworkAutomationElementBase.GetNativePattern[T](PatternId pattern)
   --- Koniec śladu stosu wyjątków wewnętrznych ---
   w FlaUI.Core.FrameworkAutomationElementBase.GetNativePattern[T](PatternId pattern)
   w FlaUI.Core.AutomationPattern`2.get_Pattern()
   w FlaUI.Core.AutomationElements.PatternElements.ExpandCollapseAutomationElement.get_ExpandCollapseState()

No issue with other Qt UI elements like buttons, lists, textbox... just this Tree.

Also togling treeitems is not possible, similar exception is thrown.
Tried to fix issue on library level with AI gave partial success for fixing ExpandCollapse

RobotFramework-FlaUI/FlaUI is calling ExpandCollapseState on an element that does not support ExpandCollapse, and the TreeItem implementation does not guard against that case
I've added such guarding which prevented raising exception and afterwards retrival of treeitem names was possible. Could you please add such "guarding" in case Tree element does not support:

• ExpandCollapsePattern
• SelectionItemPattern
• TogglePattern
  so that at least partial support is achieved (Get TreeItem Name, Select, Toogle )
  (below complete list of supported patterns)

Keywords tried:

• Get All Visible Treeitems Count
• Get All Visible Treeitems Names
• Expand All Treeitems
• Collapse Treeitem
• Select Treeitem
