Error AL0133 when using Variant by reference as parameter of function and passing record

In AL, when I define function with parameter of type variant passed by reference, I cannot call the function by passing record, because I will get error:

Argument 2: cannot convert from 'Record "tablename"' to 'var Variant'

This prevents me to do generic functions consuming any record and returning the modified record back. It was possible to use var Variant parameter in C/Side and pass record.

Create e.g. function like this:

Try to call it with two records. You will get the error in "PROBLEMS" section of the VSCode.

Workaround:
Use variant variable, assign the record, use the variant variable as parameter, assign the variable back to the record after the call. But why should I do this?

AL Language: 3.0.124247

Reproduce the function call described in the issue by passing two records to a by-reference Variant parameter and inspect the diagnostic in VS Code's PROBLEMS section. Investigate the AL compiler's argument-conversion handling for records and var Variant parameters; done means the call is accepted without AL0133 and the modified record is returned as described.
