jsfiddle js panel size is stuck! How do I reset it?

Question

Image says it all I think:

The draggable for resizing the js/html panels is gone and that js pane is too small! The big problem is that this issue persists after restarting my browser, clearing the cache, and deleting cookies. How do I reset this so I can use jsfiddle again?

Answer 1

Please run Layout.setWindowSizes(null) from console

Answer 2

As of December 6, 2018, the current answer to this question no longer works due to a rewrite of the JsFiddle site that happened sometime in June/July of 2018.

1. Press F12 to open DevTools (Chrome) or Debugger (Firefox, Edge).
2. Navigate to "Application" in Chrome DevTools, or "Storage in Firefox/Edge Debugger.
3. Find "Local Storage".
4. Find www.jsfiddle.net.
5. Delete any entries/keys labeled as grid_*-split-sizes (eg. grid_1-split-sizes, grid_2-split-sizes, grid_3-split-sizes).
6. Refresh jsfiddle.net webpage.
