# Mention editor contract
|
|
|
|
Autocomplete inserts a full literal label followed by a separator. Full labels
|
|
may contain spaces; internal spaces must not be mistaken for the final boundary.
|
|
The immediate next typed character goes after the separator even if the browser
|
|
remaps the DOM caret to the highlight edge. Explicit ArrowLeft or click cancels
|
|
that settlement so users can intentionally edit a mention. Plain typed tokens
|
|
retain their existing behavior; this does not change recipient resolution.
|
|
|
|
Regression coverage: `mentionHighlightExtension.test.mjs` simulates chip-edge and
|
|
whitespace-run rewrites, internal spaces, and deliberate motion. The ordinary
|
|
member browser cases in `mention-spacing.spec.ts` test immediate typing and
|
|
ArrowLeft without requiring remote discovery or invitation; `mentions.spec.ts`
|
|
also covers clicking chip edges and insertion before existing text.
