Function getPersonalizationPayloads() in common/personalization.js returns 1 item instead of all.

I noticed that this function is using "find()" instead of "filter()". find() will return the first item instead of all items.

Open common/personalization.js and inspect getPersonalizationPayloads(). Verify how the current find() call selects one item, then confirm that the function returns all matching items as requested by the issue. Done means the function no longer limits the result to the first item.
