Tooltips / UnitExists("mouseover") == false on certain units

[sezz]

Sorry, no idea how to describe this properly as english isn't my native language.

There are currently a lot of units ingame that return false when checking for UnitExists("mouseover"), so my tooltip modifications don't work because I can't get any information about the unit that belongs to the tooltip and the tooltip stays hidden.

This can be easily tested at Bladespire Fortress in Frostfire Ridge next to the Flight Master with the Frost Wolves and Frostwolf Peons:



Tooltips are correctly displayed when using no tooltip addon or when I target them (it also doesn't work with PhanxTooltip, but that's the only other tooltip addon I tested).

Also the name text is green , but they are neutral (UnitReaction() returns 4 when I target them and the default Blizzard tooltips also show the name in yellow), so maybe it's only a bug?
