0037504: [UX] SEARCH filters behavior is not the proper one

Description

Right now, after apply a product characteristic filter, a list with several products is returned.

If we press again the same filter, only the options(s) that could apply to this list of products is shown, while it should be shown all the options that could apply, taking also into account the other filters. This is the way other applications work.

So, instead of showing just the selected option, it should show all the options that would be shown if this filter has been never been executed (as I have said, this does not mean all the possible values for this product characteristic, since there could be already other different filters from another different product characteristics that could cut this option list). Of course, the already selected option(s) should be displayed like that.

In other words, each filter should show all the options that will return results.

Here it is a video showing how WebPOS works vs how Amazon works:
