I have a query which selects flags of a certain color (and I display this query in a panel).
It's a bit annoying to use because it does not return results in a consistent order. Refreshes for example are liable to shuffle around the results. This makes it hard to find flags that you're used to seeing at certain spots. Old flags flags can appear at the top, or new flags can show up in the middle, etc.
An unfiltered query (all flags) does not have this issue; it consistently returns things in the same order. It looks like there is just no ordering applied when selecting filtered by color.
