Parsoid/Todo:Semantically insignificant whitespace round-tripping

From mediawiki.org

Tracked in bugzilla:39564

We need clean diffs, including semantically insignificant whitespace such as extra spaces between attributes in an HTML tag.

Possible solutions:

  • Tracking all semantically insignificant whitespace in rt information.
    • Advantage: works with any client
    • Disadvantage: a lot of work and rt info / code bloat; high cost/benefit
  • Selective serialization of modified DOM parts
    • Advantage: better cost/benefit ratio
    • Disadvantage: adds a burden on clients to mark modified parts of the DOM
