Dropdown key inputs stolen by JLab when the dropdown is collapsed

Question

Dropdown key inputs stolen by JLab when the dropdown is collapsed

courtarro opened this issue 4 months ago · comments

Description

When a Dropdown widget is collapsed, any keyboard inputs supported by JupyterLab are intercepted and interpreted by JLab instead of the dropdown.

Seems related to #3836, which is still open but the discussion suggests it was fixed long ago.

Reproduce

Create a cell containing the following code:

import ipywidgets as widgets
from ipywidgets import interact
@interact(name=widgets.Dropdown(options=['1', '2', '3', 'A', 'B', 'C']))
def report(name):
    print(f'Output: {name}')

Execute the cell
Click the dropdown and press the A key on your keyboard.
Observe that the "A" item in the list is selected (correct behavior).
Click the "1" item in the list to select it.
Observe that the dropdown has collapsed and the border is blue, indicating that it should have focus.
Press A on your keyboard again.
Observe that JupyterLab adds a cell above the current one (incorrect behavior) instead of selecting the "A" item in the list as expected
Click the dropdown again, then once more to collapse it.
Press the up or down arrows on your keyboard
Observe that JupyterLab changes cells (incorrect behavior) instead of changing the dropdown value as expected

Expected behavior

I expect that, when the dropdown widget is blue, any keyboard inputs that make sense in a normal dropdown will be interpreted and executed by the dropdown, not by JupyterLab.

Context

This occurs on a brand new install of JupyterLab and ipywidgets from PyPI.

ipywidgets version: 8.1.1
Operating System and version: Windows 10 22H2 (build 19045.4170)
Browser and version: Chrome 123.0.6312.86
