Please see the attached patch, it'd seem this is exactly the fix that's
expected here. Basically, the problematic check is specific to Rust
treesitter mode, so shouldn't be executed in other languages. The patch
factors out the entire check to a separate function and adds additional
condition of (eq major-mode 'rust-ts-mode).

Tested in tsx-ts-mode, it fixes the problem.
