When doing certain operations in a repo (ex : Fetch, Pull, etc. ...) or sometimes when the automatic refresh takes place, the left side menu showing my repo's branches and the remote repo's branches collapses. This is very annoying since I usually change between branches often and having the list of branches collapsed all the time is very annoying.
This is something that changed in the 2-3 latest releases. The first version 2.x did not have that bug and the version 1.x never had any issue similar to that.
