Occasional Errors in GridView Activation

[metallibus]

I wish I could give better repro steps here, but I'm not really sure what's causing this - I get very rare instances of this bug so I can't track down exactly what is doing it.

What may be interesting about the context here is that I do use larger "windows" made up of arrangements of a variety of Nova controls, and I call SetActive(...) on the root object and that tends to be when this happens.

The only other noteworthy tidbit here is that I've seen it in some of my "when this control enables, activate this tab, which enables this part of the hierarchy, which contains a GridView", and that GridView may very well have contained some number of items the last time it was deactivated. IE, I load these windows with information about one "building" in my game, and then the player may close the whole window, click another building, and I start loading content into that window and trying to select the default tab, and boom, this happens.

Here's the relevant bit of the stack trace and error log:

Again, I don't have much reproducible here so I wish I could provide more info, but I will attach anything else I find if anything turns up.
