What happened?

When I use biome lint --apply or biome format --write with a piped file and --stdin-file-path I get the formatted / linted code on stdout, but when I use biome check --apply nothing comes out. If I remove the --apply flag it outputs a list of what it would change.

Heres the actual command I use, $path is the absolute path to my project root and $target is the absolute file path for the file I want to lint
.
${path}node_modules/.bin/biome check --apply --config-path=${path} --colors=off --stdin-file-path=$target < $target

Expected result

I expect content piped to biome check --apply --stdin-file-path=xx to output the formatted, linted and sorted file to std out.

Another weird thing is that if I pipe a file to biome format --write or biome lint --apply individually they both output the formatted / linted content, but if I pipe a file into biome format --write then pipe it's output to biome lint --apply, I get nothing. If I remove the --apply on the biome lint, then it outputs the code just fine.

After testing this with other file formats, I think this is only a problem with vue files. Piping a ts file into biome check --apply works like intended.

So when I pipe a vue file into biome check --apply nothing is outputted back, if I dont use --apply, it does output what it would of done to the whole file. Piping a vue file to biome format outputs what it would of done to the whole file, but if I add the --write flag then it only outputs the script part, not the template part, thus breaking the rest of the pipe chain.

The bug is probably here somewhere

Hello there!
I come here from biomejs/biome-intellij#50.

Perhaps I may have found the point.
When fixing a file on the filesystem, the linted output seems to be merged with the original input.

biome/crates/biome_cli/src/execute/process_file/lint.rs

Line 39 in 1f891f5

match workspace_file.as_extension() {

However, for stdin, that process is missing.

biome/crates/biome_cli/src/execute/std_in.rs

Line 108 in 1f891f5

if fix_file_result.code != new_content {

I am working on a PR #2686 right now.
