creating container app with template throws error that it shouldn't

For lack of a better place to post this:

I get the following error when trying to deploy a container app using a template. As you can read from the error message, the error is obviously not as described, since my revision name follows the conventions. Also the container app name is test-api and therefore they are less than 54 characters together. Seems like a bug, as the error message seems to be wrong.

```
{
"code": "InvalidTemplateDeployment",
"details": [
{
"code": "ValidationForResourceFailed",
"message": "Validation failed for a resource. Check 'Error.Details[0]' for more information.",
"details": [
{
"code": "ContainerAppInvalidRevisionName",
"message": "Revision name has an invalid value 'testrevision'. A revision name must consist of lower case alphanumeric characters or '-', start with an alphabetic character, and end with an alphanumeric character. The length of the revision name must not be more than a combined 54 characters with the container app name."
}
]
}
],
"message": "The template deployment 'Microsoft.Template-20260107190801' is not valid according to the validation procedure. The tracking id is 'b798306a-b958-471a-84ad-1ccb076617bf'. See inner errors for details."
}
```

Start by reproducing the reported container app deployment from the template and inspect the validation response containing ContainerAppInvalidRevisionName. No template file or test is named, so identify which template produces the shown error and determine whether the reported revision and app names are being handled correctly. Done means the issue has a confirmed cause and the deployment either succeeds or reports the actual validation problem.
