getChangedRanges rebuilds the inverted mapping for every range

Affected Packages

core, extension-link

Tiptap Version

3.31.3

Browser Used

Not browser-specific

What happened?

getChangedRanges in @tiptap/core calls mapping.invert() twice and mapping.slice(index) twice inside its inner loop, once per range. invert() allocates a new Mapping with one map per step, and the Link extension's autolink plugin calls getChangedRanges on every transaction.

Expected Behavior

mapping.invert() is computed once per call and mapping.slice(index) once per step map.

Example repro:

const transform = new Transform(doc)
for (let i = 0; i < 4000; i += 1) transform.insert(1 + i, schema.text('a'))
getChangedRanges(transform) // ~300 ms
