[Issue #513] Script freezes unexpectedly with no error written to log. Manual pause/resume brings it back

This issue happens to me randomly, too, on Chrome (Win 10).

I have a 70-line script. I made notes of the line-numbers this issue occurred over two, separate runs:

-## Run1
60
60
22
14
10
-## Run 2
69
19
29
60
70
61

In summary, it’s random, although line 60 trips most:

{
“Command”: “storeEval”,
“Target”: “var z = ‘${PriceLive}’; z = ‘’;”,
“Value”: “PriceLive”
}

On Firefox it doesn’t happen (although I have another seemingly FF-only issue!).
