RuntimeTypes don't properly ConvertTo-Expression

[iRon7]

Actual:

@{ '@Type' = [Int] } | ConvertTo-Expression

WARNING: '@type'.Module.Assembly.DefinedTypes[0].Module.Assembly.DefinedTypes[0].Module.Assembly.DefinedTypes[0].Module.Assembly.DefinedTypes[0].Module.Assembly.DefinedTypes reached the maximum depth of 20.

Expected:

@{ '@Type' = [Int] } | ConvertTo-Expression
@{ '@Type' = 'Int' } 

@{ '@Type' = [Int] } | ConvertTo-Expression -LanguageMode Constrained
@{ '@Type' = [Int] }
