fix(treesitter): outdated highlight due to tree with outdated region
Problem:
A region managed by an injected parser may shrink after re-running the
injection query. If the updated region goes out of the range to be
parsed, then the corresponding tree will remain outdated, possibly
retaining the nodes that shouldn't exist anymore. This results in
outdated highlights.
Solution:
Re-parse an invalid tree if its region intersects the range to be
parsed.
