Actually the problem: you need to change the JS code on the site page for yourself.
I tried to edit in Developer Tools (Ctrl + Shift + J) on the Elements tab, but, unlike HTML, the browser stubbornly executes the old script.
On the Sources tab, I found the necessary script, but it cannot be edited.
Help.
Chrome version: 31.0.1650.63

The solution was to switch to the old Opera (v.12 15) and use the "Apply changes" button in the source code.

Edit on the Sources tab and after editing press Ctrl+S. Scripts built right into the page will also be there (see the drop-down panel on the left)

If anyone ever needs it.
The chrome engine, it seems, should have flags for this business. I'm not sure what is relevant, but if it is, then one of the following flags (or both together) allows this:
--debug-packed-apps
--silent-debugger-extension-api
Or, if necessary, launch the browser with these flags every time , or just enable them once:
chrome://flags/#debug-packed-apps
chrome://flags/#silent-debugger-extension-api
