Error 1

Describe the bug
Lua error that occasionally occurs when interacting with either the official ui, or our addon for the Group Finder.

To Reproduce
(not 100% reproducible)

1. Tab into or press the refresh button in the LFGTool

Screenshots

Additional Context
This error seems to also occur even without LFGBulletinBoard installed.

I think it may be happening when you call C_LFGList.Search close to a LFG_LIST_SEARCH_RESULT_UPDATED event and blizz tries to update the frame for a now invalid resultID (meaning C_LFGList.GetSearchResultInfo for that id is nil)

Error 2 (FIXED)

Describe the bug
Taint error

To Reproduce

1. Interact with an addon generated dropdown that uses the UIDropDrownMenu API such as the "Font Size" dropdown in the main addon options panel.
2. Create/Modify/Join an listing on the blizzard dungeon finder

Error 2

OR, a hotfix, would be using the taintless.xml library and praying it works. https://www.townlong-yak.com/addons/taintless

Unfortunately, this does not seem to work. Even with TaintLess.xml, the UIDropDownMenu API taint still occurs and proccs the related ADDON_ACTION_BLOCKED error

More Context:
The TaintLess.xml hotfix only clears the checked and notCheckable keys from the dropdown buttons, which arent the only key that are accessed by the UIDropDownMenu_Refresh function in classic era.

Keys like value are also being accessed and not however being cleaned up by TaintLess, which leads to taint.

Some more context on Error 2;

This is possibly related to the fact that blizz LFG ui in classic is still using the old UIDropDownMenu api which has a high likelyhood of being tainted by addons which are also still using the old dropdown api (such as this one).

If this is the case a full fix would require completely moving away from the UIDropDownMenu ourselves.

OR, a hotfix, would be using the taintless.xml library and praying it works.

Error 2 partly fixed with #345

Error 1

So after testing. It does seem to be the case that blizzard is firing LFG_LIST_SEARCH_RESULT_UPDATED events for entries that do not exist whilst in the middle of a C_LFGList.Search query.

In the screenshot you can see when C_LFGList.Search is fired and when its associated LFG_LIST_SEARCH_RESULT_UPDATED event is fired, you can also see the 3 results the game tried to update mid search which failed to exists when calling C_LFGList.GetSearchResultInfo
