Thread:VisualEditor/Feedback/HTML output from template leaked into wikitext/reply (2)

I've seen several of these recently. The mess gets cleaned up if you edit anything on that page in VisualEditor again. (You'll get a warning about a potentially corrupted edit, but it's actually un-corrupting the page.) The cleanups, but not the original problems, are listed in RecentChanges under "visualeditor-needcheck".

I haven't been able to find a common theme. It happens on multiple templates, multiple browsers, Macs, PCs, and Linux.
