az interactive JMESpath with `??` is not the same as with `--query`

In az interactive mode you can use `??` to get the last command output and `??[jmespath query]` according to the documentation. However, the following works on the command line:

```
az functionapp show -n myapp -g mygroup --query "contains(usageState,'orm')"
```

but the equivalent does not in az interactive

```
functionapp show -n myapp -g mygroup
??[contains(usageName, 'orm')] 
```
