Dialog is not returning focus after updating to vue 3.5

[jardakotesovec]

After recent update to vue 3.5, we encountered regression on setting focus after Dialog is closed, which is significant accessibility setback.

It seems that with vue 3.5 in some scenarios computed properties get calculated sooner than before, which makes it skip to restoration in unMounted hook.

Here is PR to address it #3687
