test: add error case: 'the previous segment must be M/L/C'

Some special svg paths can raise errors, add a test to ensure it is now fixed..

```
thread '<unnamed>' panicked at 'the previous segment must be M/L/C'

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
fatal runtime error: failed to initiate panic, error 5
