Hiding markers is still displaying clusters with size 0

Hi,
I'm currently building an interactive map with markers. So my code is adding a map with various markers, then adding a clustering and everything is working fine. Issue is appearing when I'm starting to hide some markers, by using ```marker.setVisible(false)``` and then rendering again my clusterer, with ```markerClusterer.render()```. I can see on my map some cluster with size 0 appearing where I've hidden some markers.

#### Environment details

1.Using script api ` `
2. Inside a vuejs app

#### Steps to reproduce

1. Create a map
2. Add various markers
3. Add a clustrer
4. Render it to see everything is fine
5. Hide markers dynamically, with a button click for example
6. Render again the clusterer

You should see like me clusters of size 0

#### Code example

Click on *hide* button under the map, and zoom out to see it happening.

Thanks for the help, it's driving me crazy ;)
