Mouse passthrough to OpenLayers using WPF

问题

I am currently trying to update a map within a program from OpenLayers 3 to 6.3.1 in a WPF window. However im getting a problem where the mouse isn't passed through to the map.

The software I'm working on draws a bunch of edges over a roadmap (using Basemap) to show the capacity/utilization at a given time and calculates ideal routes and stuff (similar to Google Maps). When I click on the map it should show me the avaiable data to the nearest edge in a second window, the methods for this are already implemented, I just need to find out where I clicked.

The code im using looks lke this: (shortened some stuff I am probably not supposed to share)

index.html:

    <div id="map" class="map"></div>
    <script src="index.js"></script>
  </body>
</html>

index.js:

import Map from 'ol/Map.js';
import View from 'ol/View.js';
import TileLayer from 'ol/layer/Tile.js';

import WMTS, {optionsFromCapabilities} from 'ol/source/WMTS.js';
import WMTSCapabilities from 'ol/format/WMTSCapabilities.js';

import {fromLonLat} from 'ol/proj';
import {toLonLat} from 'ol/proj';
import {defaults as defaultInteractions} from 'ol/interaction';

import 'ol-layerswitcher/src/ol-layerswitcher.css';
import LayerSwitcher from 'ol-layerswitcher';
var capabilitiesUrl = 'https://www.basemap.at/wmts/1.0.0/WMTSCapabilities.xml';

var map = new Map({
    layers: [],
    target: 'map',
    view: new View({
        center:  [0,0],
        zoom: 2
    }),
    interactions: defaultInteractions()
});
var layerSwitcher = new LayerSwitcher();
map.addControl(layerSwitcher);

fetch(capabilitiesUrl).then(function(response) {
    return response.text();
}).then(function(text) {

    var result = new WMTSCapabilities().read(text);
    var options = optionsFromCapabilities(result, {
      layer: hidpiLayer,
      matrixSet: 'google3857',
      style: 'normal'
    });

    map.addLayer(new TileLayer({
        title: 'Basemap',
        type: 'base',
        source: new WMTS((options))
    }));
});

When i am runnign it in the browser it works without any problems, but within the WPF I can't drag the map around and it also doesn't register any mouseclicks. The dragging-around wouldn't be that bad, because i can still move around with the keyboard, but the clicks are essential to the functionality of the program.

I am guessing the problem lies somewhere in the communication between OpenLayers and WPF, but on OpenLayers 3 it works so I don't really know where to look.

I would be very grateful if someone was able to point me into the right direction, because I am out of ideas.
