What happened?

I defined a dashboard varable ${var} with values 1,2,3, and some rows repeat by ${var}.
Inside each repeated row I hava a canvas button, where I used ${var} as part of the API address, e.g., https://jsonplaceholder.typicode.com/todos/${var}.

Here's the screenshot:

When I clicked the button in first row, I expect the API address would be https://jsonplaceholder.typicode.com/todos/1, but grafana resolved it to https://jsonplaceholder.typicode.com/todos/{1,2,3}
The same issue happed to query params and payloads fields.

What did you expect to happen?

If a canvas button is within a row that is repeated using ${var}, it will accurately substitute the template variable ${var} with the corresponding value for that row.

Did this work before?

No

How do we reproduce it?

1. create a new dashboard
2. define a new variable $var, with value 1,2,3
3. create a row, repeated by $var, now we have 3 rows
4. inside the row, create a new canvas button
5. configure the API address of the button to https://jsonplaceholder.typicode.com/todos/${var}
6. back to dashboard main view, now we have 3 buttons
7. click any of the 3 button, observe the API address in browser console
