"Add card" button initially not visible in Safari

Not clear what is happening, but when the index card is loaded, the add button is not visible.

As soon as something is changed, the add button shows up.

This seems to happen only when the "Support Clipperz" button is visible.

We may try to render the "Support Clipperz" button in a more streamlined way inside the Flexbox grid.
