Why is loopIndex always equal 0

I see this discussion：

construct.net/en/forum/construct-3/how-do-i-8/wait-inside-forrepeat-loop-157049

So I gave it a try:

output:

Text: 0 0 0 0 0 0 ···· 0

I found a problem. Why doesn't the value of loopIndex change

I expected was:

Text: 1 2 3 4 5 6 ···· 10

Of course, I can set a variable and add it to the loop.

I just curious, why doesn't the value of loopIndex change.

After the wait, the loop has finished. So there is no longer any loop index to be retrieved.
