textual fails to build from source due to extra whitespaces in test

[Vladimir Petko]

Textual builds from source locally, but when built by CI, the tests fails due to extra whitespaces in the returned value:

tests/input/test_input_value_visibility.py::test_input_value_visible_on_instantiation !<textual.widgets._input._InputRenderable object at 0x767b1c4be1e0>!
