I think your change improves the graphical layout of the history view but I have some style nits:

Try to find a clearer commit message for your change. Also start it with an upper case letter.

I believe you want to say that in the history view the graphical tags used to mark tags, branches and symbolic refs were not exactly aligned horizontally with the log message header of untagged entries.

Find some more comments inlined.
