Setting reverse FK relation history omission

[irfinnew]

Setting a reverse (nullable) FK relation where the FK is on a history model and the reverse relation is on a non-history model does not update the history.

E.g, DrmProperty(20).is7_platform = 231, and Platform(231).specs = [20].
Setting Platform(231).specs to [] updates DrmProperty(20).is7_platform to None, but does not record this in the history.
