Link to marker does not work when "active player only" filter is on

[Ranran]

Reproduction procedure:
- Open the marker list
- Turn on "Acrive player only" filter
- Click on the displayed list

If the filter is turned off, click it and it will respond 100%. However, when the filter is turned on, it hardly responds, but sometimes it responds.
Also, as far as I can see, there are places where it is easy to react and places where it is not.
Even in the same place, if you click about 30 times, the marker may open.

The list was constantly updating, because the total count did not match the list count. Would happen also for an empty label.

This must be broken for some time already.
