I believe this may be a related closed issue:
#396
In some cases, it appears that AlgoSigner does not attach itself to the window global. It seems to happen after a page refresh. But it's intermittent and hard to debug.
Also, noticed that AlgoSigner does not inject itself to window if opening a blank tab, or on localhost. Is that behavior documented anywhere?
Just looking for more information so I can figure out how to reproduce/debug this issue. Thanks.
