zc he 3836da0cf1 fix(parser): mixed side effects of different choices in parse_oneof (#14912) ... # Description This PR fixes #14784. <img width="384" alt="image" src="https://github.com/user-attachments/assets/aac063a0-645d-4adb-a399-525bdb004999" /> Also fixes the related behavior of lsp: completion won't work in match/else blocks, because: 1. truncation in completion causes unmatched `{`, thus a parse error. 2. the parse error further leads to a state where the whole block expression marked as garbage <img width="453" alt="image" src="https://github.com/user-attachments/assets/aaf86ccc-646e-4b91-bb27-4b1737100ff2" /> Related PR: #14856, @tmillr I don't have any background knowledge of those `propagate_error`, @sgvictorino you may want to review this. # User-Facing Changes # Tests + Formatting # After Submitting		2025-01-30 06:30:45 -06:00
