Why do I get an error when specifying a Simscape component parameter with same name as built-in Simulink parameter?

I have defined a custom Simscape component with a parameter named "position" declared only once in my component file. When I generate the library for this component, I get the following error:

>> ssc_build

Failed to generate 'tsTest_lib'

Caused by:

Error using simscape.engine.sli.internal.setupmask

Invalid inputs specified for method 'addParameter'

Error using simscape.engine.sli.internal.setupmask

Block 'tsTest_lib/Variable Area Ram' already has a built-in parameter 'position'. Hence a mask

parameter of the same name cannot be added

With same *.ssc file if we add this in Simscape component block, the error dialog reports

"PMDialogs.DynDlgBuilder.realizeChildren" (for failures in setupmask)

or

"Unable to create block dialog. If the block belongs to a custom Simscape library, please run ssc_build to rebuild the library. Please contact technical support if the error persists." (for failures in pmdlg)

The "position" parameter is already a built-in Simulink mask parameter. As a result, this causes a conflict when a Simscape parameter is defined with the same name in the component file.

As a workaround, changing the parameter name from "position" to something like "myposition" resolves the conflict. After making this change, running "ssc_build" in the package directory will successfully build the library.
