Google Maps cache icons not tapable

[Lineflyer]

Reported by some users of 2021.02.14 as well as current beta 2021.03.28-RC:

After a while of using the map I am no longer able to tap any cache icon (no reaction on tap). Only restart of the map or even c:geo (not sure) solves the problem until it appears again at some point in time.

---

All users reporting this are using Google Maps.

This is only reported rarely, so either it affects only some devices or Android versions or certain combination of settings.
I could not reproduce up to now.

Addon:
After looking through the related support tickets again it seems all of the users are using Google Maps Satellite maps. Might be a coincidence though as I was not able to find all historic tickets to doublecheck.

Coming back to this one:

Recently again three users claimed similar effects. One user tested it more in depth and reported the following, which might be helpful to track down this issue:

• It only happens if I use Google Sat sometimes also on Google Street, never on OSM
• Best chance to reproduce is, when you put c:geo into background while the live map is opened (e.g. to check your mails) then return to c:geo
• In this case the map is still as I left it but cache icons are no longer tapable, nothing happens
• Interesting enough: In such cases I can still tap on Adventure Labs and the popup opens normally, just all other caches/waypoints do not react
• To make it work again I have to leave the map and open it again

I tried yesterday evening to reproduce this, but whatever I tried i was not successful in reproducing it.

Anyone any idea from the code why it happens for all icons except adventure labs. I though this could be helpful to track down the problem?!
