install doesn't set path components permissions with -m like coreutils version

[maciej-perplexity]

GNU coreutils behavior:

$ install -m 755 -d ./path/to/dir
$ stat -c %a path
755
$ stat -c %a path/to
755
$ stat -c %a path/to/dir
755

uutils --version 0.2.2 behavior:

$ install -m 755 -d ./path/to/dir
$ stat -c %a path
775
$ stat -c %a path/to
775
$ stat -c %a path/to/dir
755

Only the last component of the path receives the desired permissions. Is this intentional?

#9254 ? @akretz Reproducible after the commit.

I can also reproduce it (with umask 002), but #9254 seems unrelated. I get the same behavior without #9254.

FWIW the comment here suggests the error may have been there for a long time - it claims GNU's install only applies the mode to the target directories, which is not what I observe in GNU coreutils 9.5
