`orientation` is not reliably set

[Groschenroman]

Describe the bug
The value for orientation is not reliably set. When testing a page with Browserstack for example, the orientation remains as portrait regardless of the actual device orientation.

To Reproduce
Steps to reproduce the behavior:

1. Add an event listener to the window resize event
2. Read and console.log the current value for orienation
3. Push the branch to test with Browserstack (or use Browserstack Local) for example
4. Open developer tools
5. The log will always say portrait regardless of the actual device orientation

Expected behavior
The value for orientation should reliably be set in correspondence with the actual device orientation.
