Repro path:

• Create a StackPanel, set a proper name to it
• Add some text entries to it
• In navigator, right click the stack panel and go to Layout, ReplaceWith, and select Uniform Grid

Expected:

• The named StackPanel is replaced by an UniformGrid, preserving the original name

Actual:

• The StackPanel is replaced by an UniformGrid, not preserving the name.
• The name cannot be fixed by hand because the name is cached as being already in use, even though in the navigator is not present

Note: Other properties are not preserved either and margins of contained elements gets messy, but not part of this report
