Issue with emoji reactions to menus in 3.5-dev

[RheingoldRiver]

What Red version are you using?

3.5-dev starting with commit f025283

What were you trying to do?

Add emojis to a menu, like this, in a specified order, with more emojis than the rate-limit

What did you expect to happen?

1. Always have the emojis print in the same order every time (we ensure that they're sent in the same order every time by our code)
2. Handle the rate-limit errors gracefully & retry as needed

What actually happened?

Through commit d7d6ab4, this was handled fine. Starting with commit f025283, however:

1. The emojis printed in a random order
2. Upon hitting the ratelimit, an error was printed to the user, and no retry happened

How can we reproduce this error?

1. Make a command that creates an embed and adds at least 6 emoji reactions, in the same order to it, it doesn't actually need to be a functioning menu. But here are our cogs if you want to install them. You would need dbcog and padinfo, and it should work with just that, the command is [p]id.
2. Run the command with commit f025283 or later.

Anything else?

We updated our bot a week ago, but the issue started today, so I'm not sure what's up with that. However, rolling back the Red version fixed the issue so there's definitely something going wrong that started with that commit. And it wasn't an ephemeral thing for just a few minutes either, it was broken for about 5 hours before we thought to try a rollback.

Seems like a duplicate of #5905, just with a different endpoint. Closing this in favor of that issue.
