Old system was hard to track in terms of usage and it's application of
'components' properties directly to elements was shoddy.
This routes usage via the components service, with element-specific
component usage tracked via a local weakmap.
Updated existing found usages to use the new system.
User search input blur would trigger the submission of the search
filters which would cause strange thing where you'd click on a search
filtered user which would blur the input hence submit, but the user
would think they've clicked the user and the page would reload but the
input had not updated at that point.
