✅ Data Selection Overlay cannot be closed if browser window is reduced

[sosiology]

Steps to reproduce

1. Go to test.visualize.admin.ch
2. Select a data set and proceed to creating a chart
3. Create a chart, then add another chart with another data set
4. Once the dataset search overlay appears, Reduce the browser window to ca. 50%
5. Click the "x" to close the overlay
6. See that the click target is not quite centred, making it seem like the overlay cannot be closed

Expected Behaviour
When clicking the X i would expect the overlay to close, it seems like the click target is a bit to far to the right.
