Does "when node <node> double-clicked" block still work?

[dulcarnon]

I have been unable to get the "when node double-clicked" block to work, either in my own scripts or in the examples like Sim and Tic-Tac-Toe.

If I start from the simple script suggested in the Help for that block, and double-click on some node on the stage, I get an error that varies a little from browser to browser:

• in Chrome 91 and Edge 91: "Uncaught TypeError: Cannot read property 'variables' of null"
• in Firefox 89: "TypeError: this.home.Context.receiver is null"

In any of those browsers, double-clicking on the script itself gives "Error a variable of name 'node' does not exist in this context".

Thanks for your attention and your great Snap mods!
