python -m venv .; source bin/activate; python -m pip install jupyter ipywidgets - Run Jupyter notebook attached to this bug report:
jupyter notebook Floatslider.ipynb. Evaluate all cells. - Click button to change the widget value to 0.7000001. Print the value of the slider: It shows 0.7.
- Click button again. Print the value again. This time it shows 0.7000001 as expected.
Expected behavior
The widget holds the same value every time.
