Bug description

In Nextcloud version 30.0.4 and Maps version 1.5.0, I get this error after adding 4 Favorites to the default map. The UI then freezes, I can't interact with any Nextcloud UI elements except for the top bar. (Not even Settings or hiding/showing map elements or clicking POIs.) Results come back from Nominatim if I hit enter quick enough, but the UI is frozen so it doesn't have an effect. Creating a new Map, refreshing the page, and searching for POIs from that map works fine. Then, oddly enough, switching back to my Default map has the UI and search working again. Hmm.

Steps to reproduce

Unsure. Add a lot of Favorites using Search. I did search for some items with no results, use the (X) Clear POIs button a few times, and encounter some lagging/freezing before giving up.

Expected behavior

The UI should continue working even if error conditions are encountered

Additional info

No response

Start by reproducing the freeze in Maps 1.5.0 with four or more Favorites on the Default map, including searches with no results and clearing POIs. Inspect the browser console for the reported VueJS and vue-select.js TypeError, and compare behavior after switching to a new map and back. Done means the map UI remains responsive when these error conditions occur.
