It seems that previewers.builtin.treesitter does not include semantic highlights

Problem

I learned previewers.builtin.treesitter is set to enabled = true by default, but it seems that the some of those semantic highlights won't be shown.

In the previewer of :FzfLua tabs, one of the buffers looks like this:

(NOTE: In both cases, the result of calling :Inspect at the keyword keymap(lines 16,17 in the previewer) is displayed at the bottom-right corner.)

But when I jumped to that buffer, the :Inspect showed me that a semantic token was applied to the keyword keymap:

Is this normal? Is it possible to show semantic highlights in both cases, so they will look the same?

"Semantic tokens" are provided by lsp rather than treesitter. There's no lsp attach on the preview buffer(which is actually scratch buffer copy-pasted from original one) so they looks different.

Ty so much, this resolves my confusion :D.

To conclude, this is normal since no one will expect an LSP client to be attached to a previewer scratch buffer.
