Conflict with "leaflet-topography": "Uncaught TypeError: invalid 'instanceof' operand L.MarkerCluster"

[RobRover]

Hope someone can help me: I'm getting an error using Laravel 9 and Vue 3.

Looks like a conflict with leaflet-topography even tough I'm not using it there, just importing it. When I comment app.js all works correctly. I tried to create a route "/#close" but did not work

Error chrome:
Uncaught TypeError: Right-hand side of 'instanceof' is not an object

Error firefox:
[Vue Router warn]: No match found for location with path "/#close"

Source map error: Error: request failed with status 404

I don't think this has anything to do with leaflet-topography. During the execution data.layer instanceof L.MarkerCluster throws an error as L.MarkerCluster becomes undefined. This is due to it being removed from the L object during the code execution (see images). I don't know why this happens though.

Regular behavior:

Error behavior:

Using the build of this branch solved the issue for me.
