fixed spacing problem for right-aligned frametitles without background

[samcarter]

For users of the right aligned default frametitle template, beamer currently inserts additional vertical and horizontal space:

\documentclass{beamer}

\usepackage{lipsum}
\usepackage{ragged2e}

%\setbeamercolor{frametitle}{bg=red}
\setbeamertemplate{frametitle}[default][right]

\begin{document}

\begin{frame}
\frametitle{title title title title title title title title title title title title title title title}
  \justifying
  \lipsum[]
\end{frame}

\end{document}

This does not seem consistent with the left aligned template:

nor with the right aligned frametitle if a background colour is set

Simple fix:

One could avoid this by removing the line

The result would look like this:

The question is: what was the purpose of this line?

• the line was added at the same time as the frametitle template, empty commit message 1d2dc8b . So no clues from there
• I thought maybe for sidebar themes, but they don't seem to need the additional spacing

We'll go for it and see if we get complaints - it's one of the Till things we have no idea about!

@josephwright Thanks for taking a look!
