Preserve unused Parsoid template properties Problem: Parsoid has a property called "i" which we don't use, but they need for round-tripping purposes. Since we were generating a structure from Parsoid data and then generating data from the structure without preserving properties we didn't use, it was getting lost. Solution: Abstract creating a template from data vs. creating it from name. Make only templates have an origin argument in their constructors, so and set it within a set of static constructors that create a template for either data or a template name. Store the original data in the former case, and use it as a base when serializing. Changes: ve.ui.MWTranslcusionDialog.js * Remove no-longer-needed mw global declaration * Move most of the addTemplate function to a static constructor in the template model class ve.dm.MWTransclusionPartModel.js, ve.dm.MWTransclusionContentModel.js, ve.dm.MWTemplatePlaceholder * Remove unused origin argument/property/getter * Add serialize method (if needed) ve.dm.MWTranclusionModel.js * Move template/parameter generation from data into static constructor of template model * Move serialization to part classes ve.dm.MWTemplateModel.js * Add mw global declaration * Stop passing origin to parent constructor, store it locally instead * Add original data property/setter for preserving unused properties when round tripping * Add static constructors for generating a template from data or by name * Add serialize method Bug: 51150 Change-Id: Ide596a0ca0ae8f93ffce6e79b7234a1db7e0586c
