Different behavior in a conditional code execution (if...) 1.21 vs 1.22

Hi Klaus, congratulations on the new version.
I have to report a problem between version 1.21 and the new version 1.22.
Using exactly the same code, there is a completely different behavior in a conditional code execution (if...).
I take a variable ("mytag") and compare it with the value of another variable passed by an argument. in version 1.22 the "if" condition is not executed, while in version 1.21 it works correctly.
To test the different behavior, click on the two icons on the right to activate or deactivate the colored icons on the map.

        for(set(i,1), i LT 21, inc(i),
            if(hotspot[calc('spot_' + get(i))].mytag == get(var1), 
                switch(hotspot[calc('spot_' + get(i))].visible);
             );
        );

Below I have attached both projects with both versions.

Version 1.21 (works correctly)

Please, where is the problem...???

Thanks Klaus for your prompt response and detailed analysis of the problem.
But also thanks for all the work done in constantly updating the krpano player.

I am "anxiously " waiting for the new version...
