Jonas Jenwald 625d4f794e Re-factor the loading-icons used in the viewer toolbars
Currently the SVG images for the loading-icons exist in two versions, for the light- respectively dark-theme, which nowadays are the only "duplicated" icons left.
The reason for this is that these icons are being used in `input`-elements, where the regular `mask-image` approach used for all buttons don't work.

To address this we add containers for the `input`-elements, such that we have a "regular" DOM-element where we can use `mask-image`.
