Description
What happened:
We have a Grafana selector that allows empty string values (''), which are valid in our context. However, when using the macro $__conditionAll, it is being replaced with 1=1, even though an empty string should be considered a valid selection.
For reference, the current documentation of the macro is as follows (README.md):
| Macro | Description | Output example |
|---|---|---|
| $__conditionalAll(condition, $templateVar) | Replaced by the first parameter when the template variable in the second parameter does not select every value. Replaced by the 1=1 when the template variable selects every value. | condition or 1=1 |
What you expected to happen:
If the Grafana selector has an empty string value '', the macro $__conditionAll should not be replaced, as this value can be supported and is valid for applying the specific condition.

Questions:
- Is there a specific reason why an empty string ('') is treated as all?
Environment:
- Grafana version: 11.1.3
- Plugin version: 4.0.8
