Describe the problem
See this thread for the initial discussion #18600 (comment)
Overlapping non-nested matches are allowed by configuration: nothing in the placeholders: machinery inherently forbids two regexes (or one regex) from producing overlapping ranges.
Solution brainstorm
- Document and implement a clear rule for overlapping, non-nested placeholder spans (e.g. merge to a single covered interval, deterministic precedence, or explicit “unsupported” behavior with safe fallbacks).
- Align highlight_string() / UI highlighting with whatever rule we choose for checks and autofix paths that rely on the same ranges.

Additional context
We want concrete examples from real projects (or realistic snippets), for example, actual placeholders: flags (and sample source strings) that produce overlapping matches.
