Checklist

• I've looked at the documentation to make sure the behavior isn't documented and expected.
• I'm sure this is an issue with Leaflet, not with my app or other dependencies (Angular, Cordova, React, etc.).
• I've searched through the current issues to make sure this hasn't been reported yet.
• I agree to follow the Code of Conduct that this project adheres to.

Steps to reproduce

...WIP

Expected behavior

Markers should always be visible when moving around

Current behavior

Initially, the markers are visible, sometimes when moving around something goes wrong and all the next renders will have a negative z-index for the markers.
