Tags in some List sub-items display in an immense font
Summary: Create a Model A which has a List of another Model-specified Type B. Make B have one or more Tag-Set Properties. In the bulk editor, the tags are displayed in header-size font, one to a line.
Justin: bizarre. I'll have to look into this...
Later: okay, stupid CSS bug. Suffice it to say, the individual Tags in a Tag Set are technically list items -- and the List code wasn't being careful enough about which list items it was trying to format. Fixed.
