Grid rearrange strategy adds selected element to elementsToRerender (#6551)

**Problem:**
Grid rearrange doesn't render the result of the rearrange during the
interaction.

**Fix:**
Quick fix: It seems in some cases (remix? dragged element is component
instance?) the moved element has to be in elementsToRerender to make
sure it is rendered into its target position during the interaction.

**Manual Tests:**
I hereby swear that:

- [x] I opened a hydrogen project and it loaded
- [x] I could navigate to various routes in Play mode
