TilesRenderer: Load order can result in children loading first, taking LRUCache space before parents #1230
Description
This can be an issue when the renderer settings trigger tiles to load that immediately overflow the cache (as happens with #1065). This can result in a case where children are loaded but the parents are not. We may need to adjust the cache eviction approach to eject tiles that should be loaded with lower priority to ensure this inconsistency is avoided.
