Note that this bug seems similar to T400013: VisualEditor deletes list-defined references if there's a reference containing an ISBN and magic linking is enabled to be fixed with 1170800 . This ticket is for documentation and to give users a point to go to when they see this happening.

Steps to replicate the issue:

• Create a page with the following Wikitext:

One <ref name="ldrOne" />

Two <ref name="ldrTwo" />

<references>
<ref name="ldrOne">Foo</ref>
<ref name="ldrTwo">Bar</ref>
</references>

• Open the page in VisualEditor
• Edit the content of any reference that's in the list
• Don't edit the content of the other reference
• Save the page

What happens?:

• The reference that was not edited got removed

What should have happened instead?:

• Just the new reference should be updated
