Steps to replicate the issue (include links if applicable):

• Type some content into a page with Edit Recovery enabled
• Stop editing without saving (so that the changes are stored in Edit Recovery)
• Start editing that page again, entering some content, and ignore the Edit Recovery popup
• Now click "discard changes"

What happens?:

• The popup closes
• The stored Edit Recovery data is removed
• Any newly-unsaved changes you've made to the page are removed from the editor (i.e. it is reset to the currently saved state of wikitext)

What should have happened instead?:

• The popup closes
• The stored Edit Recovery data is removed
• Any newly-unsaved changes you've made to the page are not removed from the editor
