Running vue-tsc and working directory vs --project

[rchl]

I'm not sure if it's a bug so posting it as a question.

In https://github.com/rchl/volar-component-types I saw this behavior that I'm not sure if is a bug or expected.

I get different results whether running:

# in root directory
./node_modules/.bin/vue-tsc -p fixture

or

# in the "fixture" directory
../node_modules/.bin/vue-tsc

In the first case, the host.rootPath in the Volar module is the working directory (the root of the repo) while in the second case it's (as I'd expect) the fixture directory path.

Shouldn't the host.rootPath be the fixture directory path in both cases?
