Replacement breaks conditional code

Describe The Bug

Note, I've stripped most of the code to show the bare minimum for the bug

I have a .bicep file that contains the following code:

//#if(includeDatabaseContainer)
var cosmosDatabaseContainerName = '__apiNameLower__'
//#endif

In my template.json I have the following symbols:

"symbols": {
    "includeDatabaseContainer": {
        "type": "parameter",
        "datatype": "bool",
        "description": "Whether to include a database container",
        "isRequired": false,
        "defaultValue": "false"
    },
    "apiNameLower": {
        "type": "generated",
        "generator": "casing",
        "parameters": {
            "source": "apiName",
            "toLower": true
        },
        "replaces": "__apiNameLower__",
        "fileRename": "__apiNameLower__",
        "displayName": "Api Name Lower"
    }
}

The __apiNameLower__ replacement works fine throughout all my template files. But when I pass includeDatabaseContainer true as a parameter the output is not as expected.

For example:

dotnet new MyTemplate --apiName MyApi --includeDatabaseContainer true

I would expect:

var cosmosDatabaseContainerName = 'myapi'

But what I get:

myapi'
...
//#endif

To Reproduce

See the sample code in the bug description.

I've figured out the root of the issue. It happens when //#endif is at the bottom/end of the .bicep file. Then it does not get parsed, I think. When I add an extra line of code below it, everything works fine.

I've stumbled on this issue in my work and was able to find a similar workaround, but it took me a day to figure it out on my own. It's tough when errors are silent.
