VisualEditor: Advanced transclusion editor for complex templates eats parameters
Open, LowPublic

Description

If you have a complex transclusion (e.g., a succession box), and you try to rearrange the order of the items, and if one or more of those items is a template that contains a parameter, then some or all of the parameter-containing templates will silently disappear.

See https://en.wikipedia.org/wiki/Wikipedia:VisualEditor/Feedback/Archive_2014_1#Add_content_and_other_transclusion_mysteries for complaints.

Tested it in test2.

"Example: here all I did was use the "up" button four times: "up" the lowest "content", "up" the lowest s-aft, "up" the lowest "content" again, try to "up" the lowest s-aft again. Result when you want to save it: the s-aft has simply vanished :-)"

It was non-reproducible - either the issue is resolved or I am not inventive enough :( I'd like someone else to take a look at the issue - hence I've assigned some priority to it.
