Branch history no longer shown and branch marked as inactive

Since the latest TeamCity Enterprise 2020.2 (build 85487)  it looks like branches created from commits older than master no longer show the branch history unless they have new commits (and then only that commit is shown).

Previously I used `teamcity.activeVcsBranch.age.days` to 365 to get around this but this no longer seems to be working.

If I checkout master, and create a branch that's from a commit ~3 weeks older and push that branch.  Teamcity detects it as "inactive branch" and has an empty history.

It can build the tip of that branch but won't allow you to select any other commit.

I should also point out this only happens for *new* branches. Old ones work fine..

Was this change intentional?

Thanks,
