Syntax highlighting crashes/stops working for C

[its-luca]

Summary

When editing C files, the syntax highlighting sometimes stops working while I edit the code. It feels like this mostly happens if I introduce a syntax error. The issue is "buffer local", i.e. the syntax highlighting still works in other buffers. I observed that after using the config-reload command the syntax highlighting works again.

Reproduction Steps

Unfortunately I do not have a concrete recipe to reproduce the issue. I have attached a heavily truncated log, that only contains the lines shorty before and directly after the issue occured

This is intentional - we stop trying to highlight the current buffer if it takes tree-sitter longer than 500ms to parse #7028
