Don't we have the same issue above with Aliases_with_targets ?

There we are using Rules.Produce.Alias.add_deps which correctly registers the deps without introducing any anonymous actions. Here we are using Super_context.add_alias_action which is creating an anonymous action. This is a wrapper around Rules.Produce.Alias.add_action which for our purposes is probably not what we want.
I've gone ahead and replaced this with Rules.Produce.Alias.add_deps here as well and added a test to make sure the with_targets version is treated the same.

I can confirm that with_targets did not have the issue I am fixing here.

If you look at my latest push, there is a test for both with targets and without and as I mentioned the one with targets does not run twice. The bug I am fixing here only appears to be an issue for rules with no targets.

In a similar vain to #11547 user defined rules were generating multiple actions which meant building both aliases at the same time was running the action twice. We fix this issue by making the other aliases rely on the first alias in the list. (This might be fragile lets see).
