FA-11408 / Accessibility interaction semantics / Member archive
Name flattening leaves line breaks as spoken separators · case 03
Text fragments produce excess spaces or lose intentional nonbreaking characters.
Case contract
Join text fragments with one ASCII space, collapse runs of ASCII space, tab, CR, LF, form feed and vertical tab to one space, and trim those ASCII characters at either end. Preserve nonbreaking spaces and other Unicode characters exactly.
Why this case matters
A controlled offline accessibility-data model. It isolates the stated contract; it does not simulate browser accessibility APIs or claim full ARIA conformance.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| ASCII line boundaries | " Item\n 3\t name " | "Item 3 name" | Failed |
