Whitespace getting trimmed from value

[WinThuLatt]

[sectioname]
prop1=
prop2=

For the example above, with the version installed 2.5.2, it trims the 5 white spaces of prop1 and 1 whitespace of prop2.
I am not able to find this TrimProperties bool when trying to set it from IniParserConfiguration.

Sample code from button.

IniParserConfiguration iniparserConfiguration = new IniParserConfiguration();

        iniparserConfiguration.TrimProperties  << not available. 
        
        var parser = new FileIniDataParser().Parser.Configuration;

        var testIni = parser.ReadFile("test.ini");
