- Edit [[mw:API:Meta]] in VisualEditor
- Select the "MediaWiki version 1.8" template
A popup appears showing the template's correct name ("MW 1.8").
- Open the transclusion editor for the template
VE thinks it is editing a template called "MW 1".
Also note that when you try to insert a template with a period in its name, like "MW 1.8", you get a whole lot of suggestions for "MW 1".
