test are failing in version 3.0.51

build without test works; but tests failing

```
tests/test_formatted_text.py::test_split_lines_3 FAILED
tests/test_formatted_text.py::test_split_lines_4 FAILED
```

eg. this breaks autom building (installing via packet manager) in arch. as #1988 does a couple of weeks ago..

thx for your free community work, though <3
