Research direction
Investigate the HTML completion provider in VS Code, specifically the handling of string literals. The bug occurs when an unclosed string like `type="che` triggers a completion that deletes text after. Look at the completion insertion logic in extensions/html language features/server/src/htmlCompletion.ts.
