Copied from English Wikipedia:
Editing Gol Transportes Aéreos Flight 1907#Criminal proceedings I added two cleanup templates, {{update}} and {{prose}}. In the visual editor the two templates were differently left-aligned and different lengths, despite saving and displaying correctly. Reopening the page in the visual editor, the templates appear at their correct size and alignment, but do appear with an apparent blank line between them. Thryduulf (talk) 14:04, 12 July 2013 (UTC)

I could replicate this on Firefox (Windows 7) but not Chrome.
