this happens if parsers are installed but highlight is set to false.
So parsing the buffer with treesitter will automatically apply them to
the buffer but because treesitter highlighting is disabled it will
change the buffer. Its stupid and i dont know why you want parser
installed but highlighting disabled but whatever.
We just dont calculate highlights for people who have highlight set
to false
Because Elixir source code can contain `|`, the removed substitution
sometimes broke `lsp_document_symbols()`.
Example:
```

Closes#874
* feat: extend functionality of `entry_display.create`
- now allows passing functions or fractional values to `width` option
* refactor: cache `width` instead of results window size
* feat: use new `width` functionality for more entry makers
* fix: action mt so we can again concat actions from two different tables
- without actually changing the public interface
- without having a local table that keeps track of all actions
* this should clear actions now
we never actually called this function which is kinda a problem because
we never cleaned up previous mapping stores.
We can also make a better mappings store which has access to the keys
sequences which would help the showing actions part
* bugfix
* that should now clear everything
only tests left i think
* more tests
* cleanup
* hack: make sure all actions get cleared
* fix: finish docs and remove mistakes from merge
* fix: change order of `popup` changes based on type of change
- removes "flash" issue where popups don't update in sync
* feat: add hide / unhide preview or results and prompt
* fix edit actions while only preview window is active
* add option to start telescope without previewer -> "disable_previewer_at_startup"
* remove hide / unhide prompt and resutls, improve hide / unhide preview
* fix tests - check if popup window should be created with borders - popup.create does not support setting borderhighlight and border=false
* allow toggle preview even if preview is set to false
* reuse recalculate_layout in hide / unhide preview
* add docs to toggle preview
* check if preview window is valid window
* remove unnecessary changes
* cleanup, remove unnecessary changes
* close all previewers, refactor toggle preview code
