## Context Fixes #52022. Rainbow bracket matching could become incorrect when tree-sitter returned ambiguous bracket pairs for the same opening delimiter. The repair path rebuilt pairs using a shared stack across all bracket query patterns, which let excluded delimiters like Markdown single quotes interfere with parenthesis matching. This change scopes that repair logic to each bracket query pattern so ambiguous matches are rebuilt without mixing unrelated delimiter types. It also adds a regression test for the Markdown repro from the issue. <img width="104" height="137" alt="image" src="https://github.com/user-attachments/assets/4318bb4d-7072-4671-8fb5-c4478a179c07" /> <img width="104" height="137" alt="image" src="https://github.com/user-attachments/assets/07a8a0fc-7618-4edb-a14e-645358d8d307" /> ## How to Review Review `crates/language/src/buffer.rs` first, especially the fallback repair path for bogus tree-sitter bracket matches. Then review `crates/editor/src/bracket_colorization.rs`, which adds regression coverage for the issue repro. ## Self-Review Checklist <!-- Check before requesting review: --> - [x] I've reviewed my own diff for quality, security, and reliability - [x] Unsafe blocks (if any) have justifying comments - [x] The content is consistent with the [UI/UX checklist](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist) - [x] Tests cover the new/changed behavior - [x] Performance impact has been considered and is acceptable Release Notes: - Fixed rainbow brackets in Markdown when quotes caused parentheses to match incorrectly
