Describe the bug
In version 23.10.15, getting the following LUA error when hovering over some brokers and they do not function.
Rolled back to 23.08.28 where the issue is not present.

Additional context
Working fine in previous version (23.08.28).

Which data broker display addon do you use? Under addon Bazooka the dropdown menus from Broker_DungeonDifficulty and Broker_LootSpec are working fine under 23.10.15.

I'm using Titan Panel.

Hm, under Titan Panel everything still works fine. 🤔

If you disable all addons except TipTac, Titan Panel and Broker_DungeonDifficulty / Broker_LootSpec, do you still get this error?

I don't get the error after a /reload with this version either, so I'm not sure what triggers it.
It happened in DotI though, so it might have something to do with this one: https://github.com/frozn/TipTac/issues/257, but with 23.08.28, I've never seen it happen (not even after having the DotI error).

Maybe worth noting that the common thing in these 2 brokers is that they have a dropdown-style tooltip that has functionality when clicked, and the other brokers that don't have this issue are only info tips.

Happened again in DotI but this time only Broker_LootSpec was affected.

I just reproduced this in DotI, definitely has something to do with the issue linked above.
After getting that error, on the second hover on Broker_LootSpec, this happens.
More specifically, I did the following sequence:

1. Hover over the portal progress bar - get LUA error for the bar
2. Hover over Broker_LootSpec
3. Hover over Broker_DungeonDifficulty
4. Hover over Broker_LootSpec again - at this point, it's not working and the LUA error pops up every time

In the meantime this has been fixed. I added several IsForbidden() checks to make shure, that the tooltip isn't accessed while it's protected.
