Tag changes persist throughout entire edit history

Post edit tracker missing tags changed

Likely something for @neil related to the recent migration of #tagging into core. Noticed recently over at Stonehearth that not all tag changes appear in the post edit history. Here is one example: Tags are restricted to TL4 only, so the user didn’t attach any tags on post creation. I am pretty sure that 8bitcrab added a tag on March 30, followed by Albert on March 31, but Albert’s tag doesn’t appear. I can provide more examples if needed, hopefully this is enough.

As if the last tag change or maybe the first (who knows) is persisting across all entries, it seems to me that would explain why the post edit history doesn’t show all of the tag changes that have occurred on said topic.
