Pin-location invisible

[someren]

Describe the bug
After clicking on the map to point out the location, the pin itself is not visible.
It does appear in the next step or in the summary.

Unfortunately, it does not happen every time. Sometimes the pin is visible and sometimes not.

To Reproduce
Steps to reproduce the behavior:

1. Go to step 2
2. Click on 'Kies op kaart'
3. Click on the map
4. Pin does not appear

Expected behavior
Every time I open the map to select the location I should be able to see the pin on the map.

Screenshots
Screenshot is a bit strange. You have to trust me that I clicked on the map but the pin did not appear:

This is where the pin should have been:
