Hi,
I am using uv 0.5.4.
First thanks a lot for introducing the --all-groups option in the sync command, very useful.
However, it seems that if I combine it with --no-dev the dev dependency group still get installed:

uv sync --all-groups --no-dev

Results in all groups Including dev to be installed.

Quite surprisingly,

uv sync --all-groups --no-group dev

does install everything but the dev group as expected
