Incorrect order of operations when brackets are used.

Write 4*(3*2) + 1 in the code editor 

observed result: in the result preview the result is 28

expected result: the result should be 25

Workaround is to add brackets on every operation:
 (4*(3*2)) + 1

The following exception is thrown when translating an expression with a nested member passed to a generic method call:

ArgumentException: 'Value' is not a member of type ' VesselInformation.VesselEventType'

Edit: ExpressionChanged event stops firing in R3 2021 which is a related regression that should be addressed.

Release LIB 2023.1.703 (3 Jul 2023)
The control's template is missing because the Telerik.Windows.Controls.Expressions.xaml file is almost empty. IT misses all RadExpressionEditor related styles and templates. This is valid only for the .xaml file coming from the "Telerik.Windows.Themes.Windows.11.dll" or the "/Telerik UI for WPF installation folder/Themes.Implicit/NetCore/Themes/Windows11/" folder.
