Misses some files but catching others in big workspace

[Narfinger]

Summary

Running
'cargo fmt --check -- --config unstable_features=true --config binop_separator=Back --config imports_granularity=Module --config group_imports=StdExternalCrate'
on servo github (revision f3bdb24d2a43853721ea757fee704ef250df9c56) shows everything is formatted ok
but the same command with --all (cargo fmt --check -- --config unstable_features=true --config binop_separator=Back --config imports_granularity=Module --config group_imports=StdExternalCrate) shows that the files 'components/script/dom/stream/readablestream.rs' and 'components/script/dom/webxr/xrsessions.rs' have their imports not correctly sorted.

Other files in the crate (components/script) get correctly formatted.

Meta

I am not sure if this is expected behavior or a bug but it is weird that it only seems to affect these few files.

I cloned the servo repo and checked out revision f3bdb24d2a43853721ea757fee704ef250df9c56. I ran the following command from the root of the project:

cargo +1.95 fmt --check -- --config unstable_features=true --config binop_separator=Back --config imports_granularity=Module --config group_imports=StdExternalCrate

and

cargo +1.95 fmt --all --check -- --config unstable_features=true --config binop_separator=Back --config imports_granularity=Module --config group_imports=StdExternalCrate

I wasn't able to reproduce the issue using rustfmt 1.9.0-stable (59807616e1 2026-04-14)

removing --config imports_granularity=Module --config group_imports=StdExternalCrate reports errors independent of presence of --all for me.
