Code review comment for lp://qastaging/~azzar1/unity/fix-977817

While this does fix the issue with the missing column when the filters are expanded, it does not stick to the padding-requirement from Design for the horizontal space between different tiles/cards. But that's a larger and more general shortcoming of the mixture between fixed pixel-sizes and dynamically adapting UIs. Certainly something we can't fix within the scope of an SRU.

So approved for now.
