get:focus doesn't work in other than main-locale

[delz-dev]

Describe the bug
{{ image | get:focus | background_position }} doesn't output correct values in other than main-locale.

To Reproduce
Steps to reproduce the behavior:

1. Define focus point on image in main-locale and other locale
2. {{ image | get:focus | background_position }} in main locale: output correct
3. {{ image | get:focus | background_position }} in other locale output is always: 50% 50%

-> workaround: {{ asset:image }}{{ focus_css }}{{ /asset:image }} always outputs the correct value in every locale …

Expected behavior
Should output the per locale defined focus of an asset: p.e. 57% 50%
