sortName causes seemingly random line breaks in font view

[federicoparra (Federico Parra Barrios)]

I found that the existence of a sortName versus no sortName causes the line breaks in font view:

On checking I found that in a given line, each glyph has a sortName, and in the next line, sortName was empty.

True, I can reproduce. Will file a bug report.
