useFocusWithin stopped working with Vue 3.4.13

[mitjans]

Describe the bug

The useFocusWithin utility is not working from Vue version 3.4.13 onwards.
Additionally, the following warning is thrown on Vue version 3.4.19 (the latest one). This warning only appears in this version.

[Vue warn] Computed is still dirty after getter evaluation, likely because a computed is mutating its own dependency in its getter. State mutations in computed getters should be avoided.  Check the docs for more details: https://vuejs.org/guide/essentials/computed.html#getters-should-be-side-effect-free
