TBrowser doesn't correctly parse branches with "." in the master branch name

My TTree has subbranches made from objects of the same class. To keep the names distinguishable to Makeclass I've appended a "." to the master branch names, as documented in the TTree::Branch documentation and discussed in https://root.cern.ch/root/roottalk/roottalk00/1691.html. TBrowser however does not correctly parse these names and so gives incorrect leaf plots. I include a TFile, a script, and a screenshot demonstrating the problem. To reproduce the problem browse down as shown in the screenshot and compare to the direct projection.
