Description
**Describe the bug**
A prim that has been marked or unmarked as instanceable does not have the selection highlighted in the viewport.
Similar to #2651: it appears to be selected in the Outliner, however, the highlight is not displayed in the viewport. If we try to re-select the object in the viewport or outliner, it does not appear. It only appears after you move the prim and then, re-select it.
**Steps to reproduce**
Steps to reproduce the behavior:
1. Open `Kitchen_Set_instanced`
3. Select `ChairB_1`
4. Right click and select "Unmark as instanceable"
Notice that the `ChairB_1` is selected in the outliner but it is not highlighted in the viewport. The same behaviour can be observed if you open `Kitchen_set` and "Mark as instanceable"
It also prints the following error in the script editor:
`// Error: Couldn't find primInfo for cache path /Kitchen_set/Props_grp/DiningTable_grp/ChairB_1
`
**Expected behavior**
We would expect the selection highlight to reflect what is selected in the viewport.
