[JENKINS-65851] Scan project not picking up a lot of branches

When project branch scan, sometimes all branches will be detected, other times only a subset of branches will be detected. I haven't been able to reliably reproduce it. It seems random.

In the example below, it is only detecting 96 branches, but there are 281 branches in the repository.

 

Additionally, unsure if it's related to the same issue, often branches will get randomly crossed out.
