How to know if a tag has history

What is the Python script equivalent of looking at the tag browser:

and seeing that there is the "has history" icon?

system.tag.readBlocking(["someTag.HistoryEnabled"])

All of the properties below a tag can be read like this:

The screenshot shows a gold scroll for history which suggest 7.9 or earlier, for which neither readblocking nor HistoryEnabled exist :\

Despite not appearing in the tag browser, it appears to resolve; I'm not really familiar with 7.9's tag system to understand how:

system.tag.read("abc.HistoryEnabled").value

Yes, this is specific to 7.9.

I thought I added the Ignition79 tag, but it didn't work. I tried again just now with an edit and it appears to be added.

That is also true on my system: it is not shown in the tag browser, but it does resolve and has the correct value.
