`./x t .\tests\ui\delegation\` (with relative path) stopped working on Windows

The day before yesterday (811367e on main) ./x t .\tests\ui\delegation\ worked fine on Windows, now (793b589) it can't find tests. Such relative paths are the output of VS Code terminal completion.

Output:

Building bootstrap
    Finished `dev` profile [unoptimized] target(s) in 0.08s
ERROR: no `test` rules matched [.\tests\ui\delegation\]
HELP: run `x.py test --help --verbose` to show a list of available paths
NOTE: if you are adding a new Step to bootstrap itself, make sure you register it with `describe!`
Build completed unsuccessfully in 0:00:00

However ./x t tests\ui\delegation\ works fine.

I wonder if this is unintended effect from #160855, I'll need to try this on windows locally.

The same happens on Linux.
