Wrong component property dialog is displayed

It looks like the first component properties dialog that is opened is shown for every other container that is opened. Only the component title seems to get updated.

Steps to reproduce:

1. Login on https://cms.demo.test.onehippo.com/?0 and open English website
2. Switch to edit mode
3. Click on the topmost bannercarousel where an experiment is running
4. Close the component properties window by clicking on the cross in the top-right corner
5. Click on the Featured products container
6. Expected: featured products container is shown
   Actual: bannercarousel container is shown (although the title shows "Featured products")

Everything works fine if in step 4, the window is closed via the 'Close' button in the bottom-right corner. It's the close button in the top-right corner that 'triggers' this issue.
