Investigate potentially failing `test_should_set_chmod()` test

[swissspidy]

This is a follow-up to #57774, which added a suite of new tests in 6.5. Since that milestone is soon closing, I am opening this to further investigate the \Tests_Filesystem_WpFilesystemDirect_Mkdir::test_should_set_chmod() test, which seems to fail on a certain host. See ​https://make.wordpress.org/hosting/test-results/r57860/wpmudevbot-r57860/

This could either be an issue with the host, core, or simply the test itself.

This test is also the last one with an is_windows() check. Would be good if we could get rid of this env-specific check and maybe rely on comparing with FS_CHMOD_DIR instead.

Hey @swissspidy ,

Just commenting here to inform that we fixed the test from our side so it should be running fine now example: ​https://make.wordpress.org/hosting/test-results/r57860/wpmudevbot-r59516/ .

It was kind of a false-positive basically, I had the test running from an extra user and umask was kicking in. The test runner is being executed from the same user that handles the services now so it should be good :) .

Awesome, thanks for sharing that update! I guess we can close this one then :)
