Testing version: Bear 2 (Mac)
What were you doing: Renaming a tag with many subtags under it. All tags had custom icons.
What feature did you use: Right-click menu / Edit Tag
What happened: Parent tag was renamed properly and maintained its custom icon but all the subtags under it lost their custom-assigned icons and ended up with the default #
.
What did you expect to happen: Subtags should retain their custom icons even when their parent tag is renamed.
