Bug with Tag Browser Icons:
I have a composite tag-like column which splits up and dedups any hierarchical tags (e.g.
Fiction.Animals.Cats, Fiction.Mystery.Cozy Mystery becomes
Animals, Cats, Cozy Mystery, Fiction, Mystery). I will post the template if needed, but I think any partitioned (or hierarchical) category should work for replication purposes.
When
Category Partitioning Method is set to either
First letter or
Partitioned in Preferences > Look & Feel > Tag Browser, it shows the partitions rather than the actual tags:
The only way to show the actual entries is to disable partitioning entirely or add it to
Categories not to partition.
I've not tested what would happen if I disable partitions, add an icon, and then re-enable partitions, but I suspect it wouldn't work.
I've also noticed a similar behaviour for any hierarchical categories - this may or may not be by design, but having it display for partitions doesn't seem intended.
(Note that because of letter grouping and virtual libraries, the partitions themselves are also a moving target - what I'm showing there is "all books." In my Default VL, there's only four partitions, and my fanfic and documentation ones they de-partition entirely).
