Domain: frontend

Research direction

Read js/src/mpl_widget.js around line 272 and reproduce the resize-handle behavior by dragging beyond the notebook bounds. Inspect how the window mousemove listener uses this.model.get('layout'); the issue is done when releasing outside the notebook does not leave the handle hidden or prevent further resizing.

Written by the indexing model from the issue text.

Description

Describe the issue

If you drag the resize handle outside the limits of the notebook and release the mouse you lose the ability to resize as the handle will be hidden:
wonky-resize

This is a consequence of using a window mouse move listener: https://github.com/matplotlib/ipympl/blob/6b44a6f90cf74b12cfcf930b440010984d8a9b4d/js/src/mpl_widget.js#L272

Maybe there could be a check that it won't be resized to be larger the layout (this.model.get('layout'))?
