[Bug] When no spaces exist within a workspace, the placeholder loading indicator is visible, even though no data is to be loaded.

### How to Reproduce

Delete all spaces from a workspace.

### Expected Behavior

That no spaces exist should be explicitly stated, else it should be blank.

### Operating System

1.

~~~sh
#!/usr/bin/env sh
cat /etc/os-release | jc --ini | jq 'with_entries(.value |= (if type=="string" and test("^[0-9]+$") then tonumber else . end))| {NAME, VARIANT, VERSION_ID}' | yq -P
~~~

1.

~~~YAML
NAME: Fedora Linux
VARIANT: KDE Plasma Desktop Edition
VERSION_ID: 44
~~~
