The binary search insertion scheme in `highlight_text` works fine for small numbers of elements but does not handle large amounts of ranges well, as that will cause constant memcpying of the latter half of the vec. Bracket colorization tends to have a huge amount of entries though, so this can cause massive lags on the foreground thread. The better approach here is to just collect all elements and re-sort them once. Release Notes: - Reduced mini-stutters occuring due to large amount of bracket colorization in big buffers and agent diffs
