Treesitter highlighting not working in Workspace Symbols Fuzzy Finder

[that-ambuj]

Summary

The Treesitter syntax highlighting does not work in workspace symbol picker's file preview if the file has not been previously opened in the current session.

Reproduction Steps

I tried this:

1. hx in a project.
2. <space>S for workspace symbols.
3. <Ctrl>n and <Ctrl>p to look at previews of symbols in right window of fuzzy finder.

I expected this to happen:

The right panel to have correct syntax highlighting.

Instead, this happened:
The code in the right panel does not have syntax highlighting in most cases.
