Sorry, 4c45e14df2f4e77982ad70d6d8e3fe750edd4c37 is the tag object for
v7.2-rc2, which points to commit object
8cdeaa50eae8dad34885515f62559ee83e7e8dda.
The odd thing is that we see different behaviour; for me (with git
2.30.2) running:
git show 4c45e14df2f4e77982ad70d6d8e3fe750edd4c37
... gives me the description of the tag as per the example in the
context below.
I'm surprised that git show doesn't find that for you.

Sure; I'm just surprised as above that git show doesn't find the tag
object.
