useSource - "toRefs() expects a reactive object but received a plain one" warning

[szwjonks]

Describe the bug
Vue warns about using toRefs on object which isn't reactive. It happens for some sources, e.g.: WMS/WMTS and I think it's because props are descructured like here

Affected version(s)

11.2.0

To Reproduce
Check stakblitz with example copied from docs - https://stackblitz.com/edit/vue3-openlayers-template-du4aja?file=src%2Fcomponents%2FTheMap.vue

Expected behavior
No warnings in console, no possible troubles connected with those warnings.

Screenshots

Additional context
Warning about deleting cacheSize also is in console, but it's have separate issue

Hi.
I also encounter this problem when I try to use it in Quasar.

[Vue warn] Delete operation on key "cacheSize" failed: target is readonly.
