A recent update made it so some items have giant tooltips due to being in multiple zones, how can I possibly shrink them?

It appears as if the "Maps" preference should control this, but doesn't.

The code in AllTheThings.lua around line 3096, that builds up the mapsConcat field is what causes the giant tooltips.

That looks great! Thank you!

This part of the tooltip code is currently completely separate from the Information Type toggles, hence not being affected as may be expected.
For now I'll consolidate the display a bit when multiple maps are found into just a count of the Maps.
