Intention: Add a template and remove a non-breaking space ( ) in the same line/paragraph Steps to Reproduce: (Order matters!) 1. Begin with a page that contains the HTML code for a non-breaking space. Open in VisualEditor. 2. On the line that contains the nbsp, add a template (e.g., {{fact}}). The template should be added to the same 'word' that contains the nbsp. 3. Then remove the nbsp (replace with a plain space, or just delete the whole 'word'). Actual Results: VisualEditor added span text like <span about="g0.42287685585435686" data-ve-ignore="true"></span> when the nbsp was removed. Adding a fact template to the end of: 1 mg 2 mg 3 mg 4 mg turns into: 1 mg 2 mg 3 mg 4 mg{{Fact}}<span data-ve-ignore="true" about="g0.5170239245053381"></span> However, adding the template to "3 mg" and deleting the nbsp from "2 mg" works correctly: 1 mg 2 mg 3 mg{{Fact}} 4 mg Reproducible: Always See https://en.wikipedia.org/w/index.php?title=Wikipedia%3AVisualEditor%2FFeedback&diff=591972176&oldid=591955710 and testing at https://en.wikipedia.org/w/index.php?title=User:Jay8g/sandbox&action=history on 23 January 2014 for many more details. Found in Firefox 26 on Windows 7 with Monobook, confirmed in Safari 6 on Mac OS 10.8.5 with Vector.
This also appears if you add any template after a {{convert}} template, and then remove the {{convert}} template. If there are multiple nbsp's on the same line, them it is only the removal of the nbsp that is immediately before the template that appears to trigger it.
Probably a duplicate of bug 60897 See if the fix there resolves this.
From following WhatAmIDoing's instructions, I can replicate in enwiki and it's fixed in Beta Labs; marking as FIXED.
